W211 KW Coilover Swap Part 3
 

Hello fellow members, As some of you may know my name is Serge. I own a shop in SoCal that specializes in Mercedes Benz. Wanted to share with you another Coilover swap on a 211 E55 AMG. This is the 3rd one.

First, released air in suspension with SDS. Removed all struts and bellows. Ordered the correct parts for installation. Installed Coilovers, adjusted height and dampening. Re-programmed the Instrument Cluster, Central Gateway and EIS. No gremlins or problems with install.

Here are some pictures.

Everything went smooth, install was great. Since there is a lot of people that want the parts list. Please PM me and i will gladly pass it on. There is a total of 12 parts. If programming is needed I can also help. Enjoy and Thanks

Great Job Serge, and very nice of you to share with the community!

Good stuff, Serge. Sun seems pleased with his setup.

Appreciate you sharing your expertise.

Nice job, about how much is for the part that are need to do the job not including the coil-overs and which model coil-overs did u used, can u send me the parts list

Please send me a PM, approximate cost of conversion?

Nice Job!

Nice, PM sent

How does this affect the ride quality/smoothness of our 211's? Does handling improve?

Thanks for posting Serge! :cheers:

As everyone knows, Serge installed the first set on my car. The car has about 8,000 miles since the install and has gone to 3 track events. Chuckwalla Raceway, Streets of Willow, and Laguna Seca Raceway. Still have to go back to Buttonwillow to get a new time with the coils. I still have plans to hit A LOT more tracks in the coming months. :D I've thrown the car around quite a bit and put it through it's paces. The car runs absolutely GREAT! :zoom: The car handles day and night compared to the crapmatic. Ride quality is a little stiffer but that is because I have it set pretty stiff. (14 out of 18, 18 being stiffest) I'm sure if I were to switch the dampening to a softer setting, it would ride just as well as the crapmatic. :D

Thanks to Serge, I hope the rest of the 55k community can one day feel the difference in their own 55's one day if they choose to do so! :bow: :y

Looks good, now sell that customer some brake rotors while it's up in the air.

Awesome build!! Sun took me for a ride in his car and I was shocked at the amount of grip the car had!! Very planted during turns and virtually no body roll! Definitely a must when the car sees track time.

i'm waiting for my airmatic to go bad... :naughty:

Save time and just do it now ;)

LOL

For all the inquiries about the parts list, I will reply very sorry for the delay.

Very thankful for your efforts Serge. If I lived on the West Coast I'd be a customer.

Thanks Serge :y We do realize why you didn't release it earlier due to business and that's totally fair which makes it even the more nicer and friendlier to share with the community, RESPECT! :bow:

Can you do it on a E63??

I am not ready yet but, curious.

I'm sure he'll answer you but personally but I don't see why it wouldn't. :nix: :y

Would be nice if a lesser expensive set of coils were released. I remember paying $800 for megans on my ls430, and they honestly rode great!!

Has anyone gotten a reply via PM about the parts list?

Just curious to get the details and pricing info if anyone's seen it.

serge
interested in the parts list/cost for conversion. PM me. Thanks

Nope PM'd him on Saturday. I'm having issues with the rear end sagging after sitting a day or two so instead of the expense of replacing two shocks and two airbags I think I could buy the whole kit for less.

Hey Guys.....All inquiries have been replied. Please check pm box for parts lists and questions have been answered. Let me know.....

SERGE.... YOU ROCK!!! :bow:

Coilovers for ALL E55's... :rolf: :rolf: :rolf:

I hate the ride with the airmatic, my E500 wagon rides better in Sport 2 than the E55? There is almost no difference from comfort to Sport 1 and Sport 2! SDS shows no issues with airmatic but I'm not sure if it works right or not. Coming from the Evo 8 with coilovers I really think that this is the best option if you want to improve the handling.
Good job Serge!

Dare I say it...?

GROUP BUY! GROUP BUY! :zoom:

I'm not sure what the forum rules are, or if Serge would have to buy a vendor membership to do it but it sounds like he already has a pretty good hookup on pricing and maybe there would be a way to get an even better "package price" if a few people bought in at once?

Obviously the SOCal guys have direct access to Serge's shop for the install and programming, so we could get a few more cars equipped and maybe even get a DIY writeup on the programming for the guys (like me) who are 3100 miles away and will need some extra guidance?

-G

Group buy sounds good, what savings we talking about here?

I agree! So cal would be a long drive for coil overs :)

I'm a Number One fan! :y

Serge, I still need you to do my brakes. I've been so busy and I can only do it on a weekend. I'll let you know. . .

Rey

I got my pm.

any chance PM'ng me the list?
Thanks.

cost ??

All pm's have been replied. I am doing an R230 SL55 Coilover conversion pretty soon. Will keep you guys posted.

AAAAHHHHH SNAP! I think I know who it is too...:naughty: :bow: :y

The SL55 coilover conversion is very challenging!

very nice!! and very interested for miami shops ;)

Damn, too bad it's not me. Very tempting though.

Nice work Serge:y

O RLY? I thought it'd be you homie...:nix::rolf:

Hope all is well! :y

Lol yeah. Unless Serge is sponsoring :rolf:

How does it handle after the swap ?

Subscribed for updates on the R230 install!

Very nice! Guess I'll just add this to he wish list.

Is this the HMS shop?

:word:

What kind of lap time improvement have you seen? I just got really curious how quickly a coil over/modded E55 would do around the ring. Also really curious how she transitions through the rising blind right hander at buttonwillow. It's been 14 years since I've been there so it might have be a left hand turn. Oh and then there's the banked decreasing radius turn following it. I have fond memories of that track they're just a little foggy.

No

never received PM on the parts list.

I'm in for a group buy. Located in So Cal too!

can you pm the parts list also please :)

F can't hang with the soft ride, got a part list for a e63? Appreciate it boss

Serge, I'd love to get a parts list too if I can. Thanks.

Please pm me to receive the parts list. Thanks

PM sent! I need to do this! SAVING UP! :D

Shooooot. What can we get the price down to if that does happen?

Interested in full parts pricing when you get a chance. My 05 only has 40k miles but I know it wont be too long before the airmatic takes a dump. Thanks!

PM sent for parts list.
Thanks!

Shoot I'm at 107k on my 03 and I'm scared I'm going to lose it soon...

I've said it before and I'll say it again. Serge is the only person that I will go to for anything under the hood. Serge and John are good guys who know what they're doing VERY well. I drive an hour out of my way just to get my stuff done by him. You're all in good hands. And I talked to Sun after he had the setup on his car for a while and he only had good things to say about it.

As soon as my Airmatic goes out I'm getting this done.

can we get the parts list for what is needed besides the coilover? better yet what coilover is out there besides KW.

PM sent for parts list as well.

I found some RK Sport COs but, idk what would be the best for our cars, since it's limited to begin with...:confused:

PM sent on part numbers Serge. I do like the adjustable suspension with the ability to adjust ride height easily via STAR and thinking if we could just tighten up the back it would dramatically make a positive difference with this car.

Any reason this conversion won't work on my '07 E550 4Matic when the air shocks finally give out and my warranty is expired?

Fellow members I have lost all my pm's in my inbox. Sorry I haven't responded. Please send pm again and I will respond very soon.

Dear Serge , I sent you a PM regarding the parts list for that conversion . I also had a couple of questions for you if you dont mind . Thank you , Max

PM sent Serge.

Serge, I sent you a PM but I'm also curious what kind of time it would take at your shop..? I think a nice drive out to Socal sometime couldn't be such a bad thing :)

The install will take about 8-10hours

Did you have it done to your vehicle...locally?

Yeah, did you Hammer..?

No I didn't but I looked through an old pm from Serge to get the info on how long it would take to do the install. Serge is in Hunnington Beach which is about 5 hours south of me. I may either do this mod next year or install the race heads with cams????

Any info on this shop? Im in Vegas and looking for somewhat local shops.

If you're referring to Hyevon let me tell you they're legit. Serge is a sweetheart of a guy. I was sold on his knowledge and expertise on these cars from our first conversation and when I saw him work, all the positive things people say about him made sense.

I can confidently say that a drive from LV to HB would be worth it. Make a weekend out of it, you wont be disappointed! :y

I know...I wish I was closer to SoCal, but life is what it is :) OT, but did you hear the Australian V8 supercars are coming to Austin in spring '13.??

At the new track? Btw do you know anyone with tickets to the series?

Yeah...Circuit of the Americas or whatever...I don't think I personally know anyone with tix...All the season holders I know are going, and the only people I've heard have them are the ticket lottery winners...

Damn ok cool thx

They're going for around $350-500...Not sure if that's standing or seated LOL

Anyone hear back from Serge?

Hey Guys, Sorry its been taking a while to get back to all the pm's that I have been receiving. I am offering free information on how to do a coilover swap on your Mercedes. Please be patient..........

Aloha! I'm hoping to get this done when i pick up my e63 estate. It's a process...

Oh???? Nice nice homie! Can't wait to see how beastly you do up the AMG Wagon! I know it's going to turn heads just like all your other rides! :bow:

Cool, patiently waiting! I already have the set picked out that I'm going to use. I just need the rest of the info and Part #s so I can get to collection parts. :D

Which set?

Cool. Looked up this place based on the coilover info. I suppose one is not limited to just the KW coilovers to do the conversion. Since I'm not planning to track it, I suppose an inexpensive option would be the way to go.

I'd be careful, the mustang and IS-F guys haven't had anything good to say about KSport...That's all hearsay since I've never had them...

Good to know. I was actually leaning towards the D2's, since they appear to be rebuildable in the US.

I've read good and bad, just like most products out there. Luckily for me, I'm just a cruiser, not doing anything crazy, like racing. A good place that I was reading about COs is on a VIP forum. They have a lot of great insight on COs. I was looking at the D2s as well, until I read that they are made the same way as the KSports. So, might as well go with the cheaper ones of the 2, plus I remember reading about a bunch of pro drifters using KSports. Even though I won't be racing with them, at least I'll know they'll last a while.

OUCH! I'd find a different place to get them from. I pulled up the ones I was going to get from Octane Motorsports and on the site you linked there was a $79 sales tax... HA! Not happening.

I just linked that site to see what type of coilovers were available.

I talked to a sponsor on the Honda-tech forum who's dealing KSports and D2s. Says he can get the MB ones for $939/$899 shipped to CA; willing to do better for a group buy.

can i get a parts list PM please. Thanks

IMO I'd rather spend the extra couple hundred bucks to have an application designed/valved specifically for my car with a lifetime warranty and customer support. I'm referring specifically to KW's.

Guys. I had D2s on my Evo for many years. They may not be the best riding setup but they for sure work great for qtr mile and other spirited driving you may want to do. In addition they are extremely light. I saved alot of weight compared to my HKS setup. Also the customer service is excellent. I had an issue with premature wear on a top perch. Ther sent me out both sides for free and followed up to make sure it worked out for me. AWD Motorsports broke just about every record in the Evo world using D2s. If they made a setup for the MB i would not have an issue buying it.
Just my 2 cents

KWs are more than just an extra couple hundred bucks...they're about a thousand bucks more than what I've seen a set of D2s sell for. I don't think your reasoning makes sense, since other companies also offer coilover applications designed specifically for certain MBs, although they don't offer a lifetime warranty. Personally, I don't plan to track or race with my setup, so the coilovers are mainly to add stability and peace of mind that I'm not going to get stuck in an airmatic blowout.

100% agree.

Other than his 10/20 post, has anyone received a PM from Serge since then? Can anyone share the parts list with us? I understand the guy's busy, but if it's free info, what's the harm in sharing it openly? I really want to start planning this swap, but can't do so without knowing the specifics.

Nope, no PM yet. I'm hoping to get this done as soon as I can, that way I don't get a blow out on the suspension. Now would not be good timing at all, for that to happen.

I think what he was really saying is that the KW's are valved and sprung specific to the E55 & hopefully E63...I don't think anyone else would have that since it's never been an option, but I'm sure in light driving E350 shocks/springs could most likely last pretty well...It's not like that car is some featherweight...

Actually, the KW site indicates that the same kit is used for E55, E500, and E320...p# 15225005.

This looks like it would save a good amount of weight as well!

Would this work on a cls55 as well?

So there have been at least a few people that have got the list. Unless this is some top secret, illegal ****, why does nobody post it in here? How hard is it to copy and paste a list of parts?

Serge (who did the research) did not opt to post openly. I think property are simply honoring that. Shot a pm or give him a call. I am certain he will be happy to send you the info

Sorry cell phone auto complete whacked that out. You get the idea

i need a coil conversion for a cl500 with abc suspension...serge are you up for the challenge if i ship my car to you?????

Yes sir

I'll buy a set of coilovers, Serge =]

Sorry but they are not. I'm sure KW never tested their system on an e55, they just say it will fit an e55 because they probably don't know any better.

Serg, if you do this there will be several other ABC cars wanting done, you know that right ?

:bow:

I have already completed a W230 conversion about 2 months ago. Cannot disclose any info because customer shipped car from the east coast and doesn't want any info out. I am working on a Cl65 coilover conversion in 1 month and will be pitting together a kit for all the ABC cars. Stay tuned. Serge

I've never read through a thread so long with very little useful information. The first post by serge with pictures was interesting. The rest of it is just trying to get a parts list. :word:

Serg can we get some input toward the end of this thread.....

https://mbworld.org/forums/cl-class-...ml#post4968032

.

Still no PM... I really want to do this, more than likely with my tax return.

+1

After several inquiries, I never received a response from Serge on the parts list. I decided to deduce from the initial photos posted, what factory parts were needed, in addition to your choice of coilovers. See my attachment for the part #s.

You're basically converting your airmatic to a stock non-airmatic W211. The parts can be verified using EPC. The highlighted parts are what are likely needed. From what I've read, programming of SDS is simply selecting the proper type of suspension being used.

I'm by no means an expert or have any first-hand experience on the conversion, but it would appear it's really not that difficult to perform. If someone can chime in on the SDS programming, that would help others out, rather than keeping everyone in the dark.

I'm still contemplating going this route, or waiting til March for when Arnott Industries is supposed to be releasing their W211 coilover conversion system that will not require any SDS programming, but will include a lifetime warranty on their components. Decisions, decisions.

E55 Suspension Conversion Parts
 

Can someone PM me a list of the needed components. I might be looking at a used E55 soon. Thanks.

06SL55
 

Hi,
I have an 06 SL55. Is there an aftermarket coilover kit for the 06 SL55?

:eek: More info? This sounds promising.

that's all the info I have from Arnott. I had checked before with someone from Arnott, and they had indicated that it was coming out late 2011; a followup email changed their response to Mar 2012. They have a coilover system for W220 (S-class) so making one for the E-class shouldn't be difficult. The main difference between what Serge did and what Arnott is proposing is the use of a proprietary computer module to override the SDS warnings.

I'm just hoping my suspension will hold up til then.

Guys is it to difficult to change the suspension from Airmatic to Steel in Star?

You don't need a box to fool it or anything else, it's really simple

That's what I had understood as well. Should be very simple.

I would guess that the purpose of Arnott's system is for the DIY mechanic who doesn't have SDS available at his disposal to make that simple change.

Not to Hi-jack this thread, but if you guys are interested in a GB for KW V2's, I can help you guys out with that. :y

Has anyone received the finalized parts list? I have had the coils sitting in my garage for 4 months and am just waiting for the parts list :(


I might pull the trigger on all the parts from spinn's post just to give the conversion a shot.

I just had the conversion done 2 weeks ago over at AutoTalent and I am EXTREMELY pleased with the result and totally convinced that it was worth the cost. The car now finally drives PROPERLY.

The list of parts I used was that sent out by Serge as well as a parts list posted here by spinn. A few of the parts I ended up requesting to be purchased were not needed at the end (and I can find that out later this week what they were--cost was minimal <$20 iirc)

Thanks, Serge/Benz-Works, for your guidance on the install as well. :y

Whats a rough ball park when its all said and done for those of you who have made the switch? The thing looks hammered to the earth in post 1. Its got to be a way better solution than replacing airmatics if they go bad. I always thought 'air ride' type suspension was more show than anything... but I digress.

Great work man!!!!

might actually concider doing this as i have just been told my airmatic system is leaking

Most disjointed thread ever....

Grimm, if you would, please verify what parts from my list were NOT needed. Were there any parts not on my list that WERE needed? Thanks!

So that was your car that I saw pics of! Congrats on doing the conversion! Car rides so much better, doesn't it? :naughty: :y

DIS JOINT?

http://www.englishforum.ch/attachmen...oint_545px.jpg

After messaging Grimm, he basically confirmed that my list vs Serge's list, only lacked the rear shock-to-control arm bolt. I updated the list to include that. Also, there is a rear shock shim that comes in different sizes. My list only lists one size, which Grimm couldn't confirm whether it was the correct size used or not. A different size may be needed. Hope this helps everyone.

thanks for sharing. now I need to figure out how much this is all going to cost installed.

Saved! THanks!

Figure the OEM parts, the shocks of your choice, plus a day's garage work if they've never done the conversion before (per Grimm). Should just require removing airmatic system and rear control arm and then installation of all your parts. I would guess that it could be done in 4-6 hours time, if they've fooled around with removing the airmatic system previously.

So again.......ballpark price installed?????:nix:

Based on Grimm's install, it was around $3500. But do your own research...the parts list is there. You pick the shocks. You pick the shop. I would guess I could have it done for about $2K-$2.5K with non-KW shocks, in my area.

That is excellent news! I no longer worry about the airmatic!

Yep, you could easily switch the coilovers to H&R's and save a grand too!

Beers to you for this research! :cheers:

I haven't spent much time doing the background research, but I remember reading that the 2005 and 2006 E55s had some upgraded front suspension parts over the '03 & '04 models (CLS steering rack, and possibly different front A-arms?).... I was curious if those changes would have any effect on this parts list or if it's 100% identical for all years ('03 - '06)??? :nix:


-G

Best to compare the front axle/suspension of a '06 E55 and '03/04 E55 using EPC. If you want to PM me your VIN, I can compare it with my '04 E500 to see if there's really any difference.

Just checked back in on this thread. Thought I'd snap a quick pic of the car with the KW's installed (including one that one of the guys at AutoTalent that did the install took) and the car both aligned and balanced. May not be of much information but it might provide those an idea as to how "low" you would be able to go with this configuration (and this isn't all the way down)

Incidentally, I do not rub either.

Awsome!

How is the difference in handling?

WOW, thats sick.. Im hoping to do this conversion one day.. I think im going to own this car forever :rolf:

The handling is what one might expect from a typical coilover system. The "twitchiness" associated with highway driving, where I actually was somewhat scared to push it too much, is now gone. I often find myself going "faster" than I would have before because I don't have that "bouncy" feeling in the car.

Most importantly though is that the car is predictable. I'm more confident that it will go where I want it to rather than where it might "lean over to".

I currently have my compression & rebound settings set to 6/12 in the rear and 5/12 in the front. If I set it back to a 6 or even dial things up to a 7/12, then the car will have that same highway feel as it did with the airmatic. Those people that are running 20" wheels with very low profile tires may want to set it up that way. I, on the other hand run the continental extremecontact dws's with the forgestar 19's and so what I have it set to right now feels good for highway/city driving.

Do you know how much weight you lost?

I didn't measure, but I know that Serge did when he was installing them into the black E55 in post #1.

Going by the photos (and obviously there may be a pound or two difference in my totals), here is what I came up with:

Each of the airmatic shocks and air spring assemblies weigh in at 19.5lbs and 16lbs. So that comes out to 71lbs. The two control that are replaced weigh in at 4.5lbs each and are replaced with ones that around 6.5lbs each. Then take into consideration that each KW coilover (with perch, etc) is around 13.5lbs and 14lbs, which is 55lbs. So 59lbs total installed

So...~12lbs total? Anyone else that has done this conversion, does this sound reasonable?

All pm's have been replied. If I have missed anyone, please pm me again and I'll gladly send over the list. I cannot post prices due to not being a vendor. Serge

Hmmm...I actually expected more. Plus you can remove the pump and the reservoir and what not...maybe another 15lbs off?

Damn, that's pretty low. Great job!

PM'd ya! Looking forward to this soon.. anyone else?

PM sent! :y

-G

Do it.. I want to feel the difference before I try and do this conversion.. :naughty:

Attached is the stock front axle parts list for 06 E55 vs 04 E500.I just slapped it all together for your review, but it looks like the steering knuckle is the only difference. Grimm did the install on an 05 E55, so the parts list should work for yours, as well as 03-06 W211.

:confused: wow that's not much at all, I remember BenzoBoi saying when he did it that the SAVINGS were close to 100 lbs and at the time I was shocked because that is an amazing weight saving but 12 lbs is next to nothing. Do you think maybe it could be more since you didn't actually weigh it? :nix:

Hi

Would you happen to have a picture of the rear coilover shock arrangement?

Thanks
JJ

Just checked with Arnott Industries, and they have not even begun testing the coilover system for the W211. Still months away from anything. Looks like I'll be heading down this route when the time comes, rather than wait for Arnott.

Anyone has done the swap on a 2007+ E63 ?

spinn, can you post this for the 20076+ E550 vs E63, thanks

Also curious if anyone's done this on a WAGON. I believe the estates all have self-leveling suspension? Wonder if that makes a diff? Or is that just controlled by star, so no diff?

Sorry, don't really have the time to do the comparison at the moment. Have you tried signing up for free use of EPC online? Best way to do it is to have the Vehicle ID Number available to accurately identify the parts in question.

Not trying to look a gift horse in the mouth... But:

Are there any other options for the struts? (Bilstein,JRZ, etc?). I am not familiar with KW struts....maybe they're great and I'm just out-of-touch with who makes premium parts these days?

Either way I'd be interested to know if there are other options to choose from.


-G

I ordered D2 coil overs. http://www.d2racing.com/content/products/RS_coilovers

Are the rear dual springs? I can't tell from the pics.

H&R, still made in Germany (just like KW?) carries W211 coil overs.

In post #89, I posted a link to raceinspired.com. Just enter in your vehicle info and do a search for coilover suspensions and you'll see what's available. Not advocating the site...just used it to get an idea of what's out there.

Thanks Grant,

I don't know that company either... I guess what I'm asking is, who are the companies that provide struts for Mercedes-specific motorsports? For example, who's struts are on a Mercedes DTM-type car? It seems that they'd really have a lot of expertise on selecting the best damping rates, compression, rebound, etc.

Maybe I'm just over thinking this..... Wouldn't be the first time. :D

Ninja edit: thanks to the others for ideas and links to previous stuff I'd missed....


-G

D2 are the supplies to AMG DTM cars :) Next time DTM comes on SPEED (hopefully we won't wait until October) look on the back of their overalls near the neck area you'll see their logo.

W3rd! Thanks Grant.... :y

Gonna go study up on those D2s a bit more.

EDIT: Now hold on a minute...... Am I mistaken, or is the D2 sponsorship actually "D2 Vodaphone" (cell phone company)??

It might just be a coincidence that there is a shock company named "D2"....



-G

Here is some of D2's racing heritage :)

http://www.d2racingsport.com/profile.htm

If I'm not mistaken both the CLK63 Black Series and SL65 Black Series have KW Coilovers from the factory.

http://www.kw-suspension.com/us/kw_history.php

I have had KW V2 on my E39 M5 and E46 M3 and was extremely pleased.

Correct the CLK 63 BS has KW's

Same goes for the Viper ACR.

So they're both good...

Does this help?

There was a member doing the conversion on his wagon but not sure on his progress...:nix:

Cheers mate, that's what I needed.
I have a E55 wagon so if you happen to find a link to wagon coilover conversion it would be greatly appreciated :)

I doubt you wagon guys will be able to do a full conversion, as the rear suspension is different for the wagons, and I'm sure there probably isn't enough demand for these companies to build a kit.

http://www.ebay.com/itm/H-R-STREET-C...sories&vxp=mtr

This guy does say the H&R kit fits the wagon, so maybe?

Any chance of a link to this build?

I know I've said this before but your CL is INCREDIBLE :bow: I actually hate the look of that CL era but yours with that color combo and just the overall look changed my mind completely considering a car can potentially look like that :bow:

w211 2003 e500 sport
 

help!!! my wife's w211 2003 e500 sport airmatic passenger front and rear gone...I am considering buying the d2 racing rs coilovers or the ksport kontrol pro from ebay, this is what I can afford as of now and i WILL never go back to the OEM AIRMATIC cash cow.. any thoughts and advice. thanks

Thanks! :o:

no love for the newbie

Not sure she'll like the coilovers if she's been used to the comfort of airmatic. Fronts struts can be had from Arnott Industries and rear can be sourced either on eBay or used parts dealers.

If you are going to do the CO's KSport D2 or KW are good CO's to go with.

thanks for reply grantwoodtx! I have replace 2 airmatics in the passed already one's from arnott and one's from mercedes under warranty and I will not go back to the air suspension ever again. i have discuss this with the wife and she's on board for the conversion. I am placing order today.

interested in the parts list/cost for conversion. PM me. Thanks

did you pull the trigger?

see page 6.

finally!!! my wife e500 D2'S coil conversions is done...test drove the car yesterday from the local shop in las vegas....the ride is pretty smooth AND handles pretty well with stock height...final adjustments needed to be done as far as the height goes im gonna have the car to moderate height for the wife....total cost for parts and labor is less than $2.2k very excited to pick the car tomorrow. thank you for everyone's help for this conversion will post picture asap.

2.2k this is a great price!

Are any of the airmatic parts worth selling after the conversion is done?

No, unless they are fairly new parts.

Cool. How long was it in the shop for? Which shop? Any parts that were not used from the shopping list? Is the Star programming simply choosing the non airmatic setting? Look forward to pics.

Actually you can get about $150-$200 per strut/shock if you sell them on ebay. That'll give you back about $600+ which is pretty darn good. I've even seen people get $1,000+ for their used parts ( in total ).

What did you do the computer for the airmatic to prevent alarms. Also did you remove the air compressor?

On the D2's for the rear, are the springs separate from the strut?

CGW needs to be set to Steel Suspension and on my conversion I removed the compressor and removed the relay for the airmatic system.

What coilovers did you use?

Guess I don't understand. CGW? who sets this? Can it be done at home? through FSS? Dealer only? Never heard of it or how to set it?

:confused:

KW Variant 2. I was going to go the D2 route but when initially ordered they said 2-3 weeks to get them from Germany and then a week for UPS delivery. When They arrived in the US they called and said they were the wrong fitment so I told them to forget about it and ordered KW.

You'd need STAR SDS to set the Central Gateway. This is not a menu available through the FSS system. It can be done at home if you have STAR or access to someone who has STAR.

D2's are made in Germany? Who were you going through? Was it that they sent the wrong setup? or they don't have a proper fitment for the W211 w/airmatic? Thanks!

Yes D2's are made in Germany but the US supplier didn't have stock and therefore had to order them in from Germany. This took 3 weeks via bulk freight as I would have had to pay about $170 extra to airfreight them in. The supplier screwed the order up and had W210 struts shipped instead of W211 struts. In fact I ordered a sway bar and stainless steel brakes lines from the same supplier and they only completed the order last week when the delivered the brake lines 4 weeks after order!

Yes there is a D2 fitment specifically for W211's.

Hmmm, that's good to hear. The D2 website doesn't indicate any ties to Germany...mainly Asia and UK.

Will probably go with D2's if they're readily available. Thx!

Guess that lets me out dont' have a STAR and home or anyone around here who has access to one other than the dealer. :nix:

What part of Louisiana are you in?

w211 e500 coilovers D2'S
 

FINALLY DONE!!! VERY SATISFIED....

How much did it run you total?

Just north on New Orleans on the Northshore of Lake P.

I just spent $4,000 for front struts, rear airmatic shocks. Would have been great to have the option to go to conventional suspension.

it cost me 2.2k parts and labor and only needed rear control arm and nuts,bolts.

I have already done a E55 Wagon. It's the exact same as a regular 211 with airmatic.

D2 coilovers are a bad product. They are made in china. I would never install D2's on a 211. Stick to KW, H&R, Bilstein, or custom that I have build....

I can't say they are bad, but they are for sure chinese ( which is usually bad...lol ).

good to know! :y

Are you saying they're bad because they're made in China? or is it personal experience or customers experience? Would help if you could quantify why they are bad. I've seen some photos of some D2's that failed...but no one quantifies exactly what the driver was doing to cause the failure to happen.

got my parts (KW V2) and going to the shop on Monday to get it done. Just in time, cuz my rear air spring was leaking every now and then. Will update later.

anyone that has done the swap...have you had an alignment done after lowering your vehicle? How far out of alignment were you?

I had an alignment and a corner balance done after the car was converted to the KWv2's. I did drive the car for 2 days before having an alignment done and I did notice the car pulling to one side. Even if that didn't happen, for the sake of saving my tire tread, I'd recommend getting an alignment done. It's less costly than the amount of money you'll end up spending to have to get new tires.

Let me know if you want me to post up my alignment results. I have my car set up for around town and highway driving.

I definitely want to get it aligned after I have the work done, but have heard there's limited adjustment. How low did you go with the KWs? What did they adjust? Please do post your results. Was wondering if a camber kit is necessary if at all for the slight lowering that I'm planning to do.

Just noticed my E500 sagging all the way down to the tire on the right rear.. Anyone know a good shop in the north Dallas area that has done these conversion kits? Had one shop quote me at $1104 out the door for just replacing one airbag but they noticed the left side is leaking as well. So since both are out I figured converting to a coil suspension, maybe do a 2" drop as well. Also, how important is it to fix the airbag when its leaking that bad? Sometimes it leaks down within 30 minutes sometimes it takes over a day.

My driver's rear had a leak where it would randomly go down, depending on whether it happened to be compressed at a certain instance. Only started happening this past month. My shop quoted about the same amount to replace just the one air bag. I don't want to deal with airmatic any longer. Better to do it now.

Have you heard much about the Bilstein air spring? I see them for $659 on ebay which is over $300 cheaper then the OE style the shop would use. He also said that they don't always register correctly with the computer. Has anyone used the Bilstein?

I don't think anyone in Dallas has done the conversion...I talked to Carson at Autoscope Park Cities about it, but never got around to it...

I think factory's are rebadged Bilsteins...but not 100% sure.

Ask GrantwoodTX where he got his conversion done...though he's near Houston.

Can someone sent me the part list and price for E63 please. I haven't gotten a reply from Sergs for over 2 day. TIA!

check post#134 for my original list. Attached is my modified list.

I'm getting mine done as I type, using KW V2 coilovers. The only parts that I really needed for my setup are the shim and spring retainer for the front shocks (items 60 and 90 highlighted in orange). I purchased a used set of lower control arms off of car-parts.com for $135 and it came with all the bolts, cover, and the riveted bracket (items 170, 180, 181 highlighted in orange) that holds some wiring on the control arm.

My installer said the only really difficulty to attempt this is that some of the exhaust system has to be dropped a little to get at the air reservoir to remove it without damaging the hose. He also avoided having to drop the rear to remove the reservoir as a whole, which is what the manual says to do. This saves a couple of hours of time.

He's supposedly finishing up the front this morning, because I had not ordered the parts needed for the front. It should be fairly simple to get that installed. Then it's a matter of programming and adjusting.

Thank you very much! :y

No problem

Price wise, it's going to depend on which coilovers you order, plus whether you decide to buy new or used control arms. Most of the bolts can be reused from the airmatic setup. Labor wise, probably 6-8 hours. Since I had an extended warranty which covers my failed air spring, I've got $1K going towards labor, which should cover it all.

Posted a writeup on my conversion here.

got a quote from a local speed shop, $2600 KW coils, installation and alignment ..

may do it very very soon

I have a brand new set that was never used willing to get go for 1750 plus shipping... if anyone is interested

that's a great price for the coilovers/labor/alignment, provided you are getting KW Variant 2 coilovers and not Variant 1 coilovers.

What's the difference between the 2? Any major improvements?

Variant 1 are not adjustable for rebound; Variant 2 has about 19 settings.

Thanks :y

this is the link that my local shop sent me :

http://www.kw-store.com/products/kw-...fort-7176.html


Im not sure wheather it is the variant 1 or 2 ....

That one is neither V1 or V2. Different line of coilovers from KW.

This is the one I have and what most other people have been getting if I'm not mistaken...the Variant 2's...:y

http://www.kw-store.com/products/kw-...t-v2-7045.html

hmnn , same price but different part number ...according to their website

If ride height is your only concern, the one you posted is good enough. If you want ride height & dampening adjustability, go with the V2's. :y

not quite sure what's the real difference between the street comfort and Variant 2 is; both have adjustable rebound dampening. Maybe less lowering capabilities than the Variant 2...which I would've been OK with had I'd known.

Thank you Serge! this is a great thread!

Can this also be done with just struts/lowering springs; not coilovers?

thanks again!

yes...though will likely require additional alignment components due to the lack of height adjustments.

got it! thanks. so basically, with the additional work, its probably a wash and easier to get coilovers.

thanks again for the info!

it depends on the coilovers you get and what their range of adjustability is. The lower you go, the more likely you'll need to adjust camber/toe. Even with the KW Variant 2 coilovers, the minimum setting is still very low and I'll likely need to add some adjustable camber arm at least for the rears.

coilovers.
 

I am interested in converting my 55 to coilovers please send me a pricing on all the parts that are needed for this conversion.. 2003 E55.. Thank you very much I appreciate it.

Please pm me

I'm new to this site. And I was trying to pm you. But I couldn't figure out how.

email me at sales@benz-works.com

Email sent.

Best to take some time and read through the whole thread. I post the modified parts list at post #228.

Best modification so far!! Car goes in the direction you want it to now much better

Let me now see if I understand, the coil overs are much better than the air suspension. On this site people have been taunting how great the air suspension is and it is way advanced and better for the car and now coil overs are better?

Wish mine had coilovers from day 1. :)

You must have been reading a different site about a different car? I can't recall anyone ever raving about the air suspension on these cars :nix: the only benefit to air suspension is that you can raise/lower the car electronically

IT was this site but under w211 and raise/lower is just an expensive do da that adds expense at the cost of reliability.

The handling characteristics of air suspension is terrible.

The only way someone would say it's good is if they never took a turn "aggressively". Maybe they like the ride comfort?

Terrible - no way. Post some track times (road course) and show me a 5+ second improvement.

I think the air suspension is nice for a luxury cruiser, but I also think each design has its purpose.

All this said, I am sure I would consider going this route if I was looking at some major $$ suspension repair bills.

if anyone in SF Bay Area is planning to install some KW V2 coilovers (already purchased) on their W211, please get in touch with me. Looking to fabricate a rear shim to give it some extra clearance (to avoid alignment issues), but need the loose rear spring perch to vacuum-form a copy. Don't want to go through removing mine at this time.

what does this perch look like? I might have extra.

I doubt you'd have an extra...it's the part that sits between the chassis and the coil. It is the perch and adjustment cylinder piece in the kit.

Like a camber plate?

Not really...it's to hold the rear springs.

It's the black piece in the photo. That holds the spring within the lower control arm and it's compressed against the chassis.

Looking to 'borrow' one without having to disassemble my setup.

What kind of alignment issues did you experience ? Is it related to the coilover swap or to the "new" ride height ?

one is a result of the other, so yes to both, the coilover swap lowered my ride height. You can check out my Alignment check results. Whether it's really that bad is debatable. I would like to not have to buy a camber kit for the rear, as I think it could be adjusted a little more if there was a shim available for the spring perch. The KV V2's don't allow stock ride height and the minimum setting is 1.2" lower than stock; I'd like to be only about 0.8" lower.

That not it than. i got something like this.:confused:

Attachment 239565

Is that what was part of that KW tool kit? My kit didn't come with the tool kit. Is there a part# for it (just to see what it's for)?

The discs in front...what are they made of? Can you provide some dimensions and a side view of it? That may be what I need. The Mercedes shims/perches can't be used with the KW system, due to the need for the adjusting cylinder. Thanks!

Serge, kindly pm me the parts list. i'm seriously considering swapping out for my E320. Do you have a pic of the finished product? i'm not looking for a ride lowering kit. i just want to be rid of the airmatic system but with the same ride height maintained when i'm done. thanks.

Thanks for the info Peter! That looks like it will solve my dilemma.

What you want to do is simply buy the stock shocks and springs for a non-airmatic E320 system if you don't want to be lowered. Install is relatively straightforward, provided you have someone that is knowledgeable in removing the airmatic components properly.

Hey guys,

Airmatic has officially failed in my E55... I'm looking at doing either D2 or Kspot coilovers now... Any thoughts? Any additional parts I'll need in addition to the ones provided in the kit?

Thanks a lot! :)

http://www.ebay.com/itm/Ksport-Kontr...vxp=mtr&_uhb=1

http://www.ebay.com/itm/D2-Racing-RS...ht_1769wt_1189

I bought the ksports from vividracing in Arizona. I haven't installed them yet but there's a pdf files I believe in this thread with all the additional parts. Serge keeps them in stock ready to ship.
I'm getting my ksports installed as soon as I get back from vacation....praying the airmatic holds up to get it all done.

jump to post#228. For the Ksport or D2, you might not need the stock top mount for the front coilovers as it might already be included in your coilover package...verify if you do...the KV V2's do not come with them.

Post photos of the Ksport package prior to install...just to see what's actually included, so we can see whether certain parts aren't needed. Thx.

Thanks Spinn. I just called the D2 guys, they said all I'll need to swap them out is the rear lower control arms, and when I called the Ksport guys they said I won't need ANYTHING, they say the kit comes with everything I'll need for the install... Not sure if they know what they're talking about after looking through this thread...

Nice! And yes like Spinn said, please post some pics of what the kit includes, that would be really helpful... I want to order the Ksports, but they don't have them in stock, they're saying it will be 3-4 weeks for delivery... :/

The rear lower control arm (center) is required for all steel spring setups; you can't reuse the airmatic air spring control arm. Check a few pages back...someone installed the D2 coilovers already and you're probably right that only the control arms are needed. You can ask Ksport if their front coilover has a top mount already built-in. Depending on the adjustability of the rear springs, you may want to buy some stock shims to provide additional clearance in the rear (if you're looking for a stock ride height)...don't know what the lowering range is for D2 or Ksport. Goto www.car-part.com to buy some used lower control arms...just make sure they're non-airmatic.

Will do! Thanks Spinn :y

Wonder how the ride quality of Ksport is compared to KW. From other platforms, people have stated KW is the best. Couldn't be happier with the KWs on my E55.

Thanks Benz Works!!

Does anyone know of the exact weight savings? 12-100lbs is a big gap..

I will be able to answer this question precisely late next week when I pick up my car from the shop where it is currently getting it's coilovers installed and airmatic system completely removed.

Work in progress:

Beautiful. I've always wanted to know a more exact figure. Please let us know when this happens and snap some pics of the beast after for us!! :D

Do you have a self-levelling rear suspension in your wagon? If so, what sort of settings you need to change through STAR to avoid malfunction messages.
I would be grateful for your follow up on this as I have '03 E55 estate (wagon) and I am considering fitting coilovers. I have learned, however, that estates with self-levelling rear suspensions cannot be converted at the time.
Cheers

I will let you know, I was told that Serge has done a wagon conversion and that it is just like for the sedan, setting up the suspension settings to "steel". but I'll follow with my installer.

Serge took these picks for me of the Ksport kit. Installed last friday.

Alot, not sure of the exact number. I had no problem carrying my Ksports to my car and putting them in the trunk. Serge put my stock system in the Ksport box(what would fit). It was MUCH MUCh MUCH heavier than my coilovers. Also 1 strut/airbag wouldn't fit in the box and had to be carried seperately. No way there is only a 12lb savings!!!!

Edit: Just looked at my Fedex Shipping invoice. I'm not sure how they do weight (round up/down). My Ksport shipping weight was 50.0 lbs (w/box)
I just individually weighed everything Serge gave me back. 80.8 lbs was the total. I'm under the conclusion that my Ksports did NOT weight 50lbs as the stock parts were much much much heavier.

That's about how much my stock airmatic components weight. The KW V2 is a few pounds heavier but overall I saved about 33 lbs with the KW V2 kit. :y

Are your Ksport's shock adjustable?

https://mbworld.org/forums/w211-amg/...on-review.html

Yep, adjustable (32-way). :y

32!..Holly cow!:eek:

:D

Ohlins :)

How much were the ksports? And the whole conversion installed?

Coilovers: 1100 shipped
Stock Parts(BenzWorks supplied) & Labor 1475
I dropped the car off Friday morning and it was ready that same night.

(flame suit on)

Ksport could make a 99 way adjustable coilover. It still doesn't fix that fact that it is and will always be a generic coilover that can be slapped onto any car which fits it.

The KW coilover was built for the W211. The valving was spec'ed out for the loads imposed upon it by the weight of the W211. I think it's reasonable to be worried about the longevity of those valves on the Ksport since the W211 is significantly heavier than the other cars this same shock can be installed on.

I hope that those with the Ksports can prove me wrong over the next several months/years that this is a non-issue. But ultimately, until then, why go with something that was never designed for the particular chassis in mind? Just so you can save a few bucks?

Talk about turn around, damn.. Thats quick :y

Member MBTEK has already done it. His Ksports have been in over a year and seen over a dozen 1/4mi trips last time I talked with him. He has had zero issues and no ride complaints. I don't know why people are so quick to dismiss something they haven't tried themselves.
Additionally Ksport's description on vividracing regarding valving:
"The valving of each set is matched to the springs installed for unmatched ride quality and reliability."

+1.

Easy answer too many don't tell the whole truth.

Some news:
So the Wagon has a different Spring/Shocks system in the back, basically the Wagon shock is shorter and the spring rate is higher (thanks to a higher rear weight bias). After a lot of back and forth with a number of vendors we were unable to source an existing shock that fits the back, so we have KW build us a custom variant 2 set specifically for the Wagon, this will take few weeks, will keep you guys updated.

This is what I initially believed to be the case. Glad you have figured it out. :y

Got some pics of your car's current ride height? How much gap do you have? Did Serge install the rear pins to center the rear spring perch to the body?

Aw man, are you going to make me post pics of my car? I sent you that PM telling you I hate my rims, lol. I wil get pics but have to post a disclaimer first.
Disclaimer: Right rear tire developed a slow leak over a week or so. Took the car to discount tire. Right rear rim is CRACKED!!! I was forced to purchase rims/tires on the spot.

I will get pics today.

LOL. Just curious if your finger space is equivalent to sticking your hand(fingers) in level with the tire/ground. I had to install the factory shims to get my rear up that height, otherwise my wheels were slightly tucked before that mod.

Thank God i found this thread! just wondering if anyone has used H&R coil overs for their conversion? i know they are a good brand and i have used them on other platforms but i was just curious as far as our w211 goes. we are a distributor at my work and i can get a good deal on a set so i figured i would go give them a try. almost forgot is there anyone here that is in the seattle area with access to a star? i would gladly pay for your assistance

Coilovers baby!

Sad to see that it went, but glad to see your building it better and stronger with coils! Can't wait to see and hear your impressions! :y

I almost pulled the trigger on some H&R, but went with the KW's. Tirerack had a pretty good deal on the H&R. I talked to one of the H&R reps and I think at the time there was low stock on them in their factory. If you can get a good deal, they wouldn't be bad way to go. The shocks are not adjustable though...if you're OK with that.

TimeToy - Is there a way to trick the system into thinking your air suspension is fine ? I would suspect if left undone, it will set the car into limp mode. (Just a guess based on other MB items...)

it really depends on the situation of the warning message. It could just be that the compressor is unable to pump up the air springs fast enough due to a leak; it's not a complete failure. Concern would be if it's dropped on one side (or all) and it doesn't go up when you press the lift button or the compressor burns out due to trying to compensate for the leak continuously.

Got a hell of a deal on these, just waiting of the lower arms, and upper strut mounts ect... If anyone wants to share info on the stuff needed to reprogram the gateway please shoot me a pm, I'm also looking for the official parts list, I see what's needed from the pictures but it would be nice to have, i know the rear lower spring mounts/arms are needed, the front upper strut mounts but not sure if there's anything else I'm missing...


Thanks,
Marc

So I have an E63 Wagon.

The W211 sedan KW v2 kit doesn’t quite go on the Wagon. The rear suspension on the wagon is different that the sedan, the shock is shorter and there is more weight on the back, so the spring rate has to be different.

ACG in San Diego did the install, the front fit in, no issue, but the back need a different set of components, KW built me a custom spring with a higher rate, it took them 3 or 4 weeks. The real difficulty was to find a shock that can be installed in the back. Right now I’m running a H&R shock built for the E350 Wagon, while KW is building me a custom shock (don’t hold my breath...). As always a huge thumb up for James and crew at ACG for taking care of business and make sure that a solution was found.

I spare you the other issues that I have encountered along the way, that are not related to the coilover install, like failing K Mac rear toe and camber bushings (3 sets) or road hazard that ruined a PSS tire and an HRE wheel (currently running temp 17” in the back).

So I got the car back a couple of day ago, and even with the wrong size tires in the back, the ride is so much better; More compliant, much less crashy on pot holes and uneven surface roads. I found the ride to be overall much more comfortable and more sure footed. I have not tried high speed cornering yet, as the 245’s all-weather tires in the back are screaming for mercy even at moderate load and medium speed.

I am not out of the barn yet, as I still want to get KW v2 shocks for the back and I’m currently waiting for HRE to build me a new wheel. I will post pictures when the car is sorted.

Overall even with the hassle, this is not time nor money I regret to have spent, the ride is so much better...


The airmatic system didn't went bad (I just have 30k, it just went out of the car. I'll sell it classified soon)


STAR has been coded for steel springs. I was told by numerous people that one can’t remove the warning on the instrument cluster on E63. The reason, I was told, being because the cluster is AMG specifics and that all AMG comes with the air suspension, and that the air suspension is coded directly in the cluster. If someone has a solution, I’m all ears. Also all the airmatic components have been removed from the car.

It can't be that hard - you just need to find the trigger or sensor that is setting the warning and figure out how it operates - voltage or ground. If you have a schematic, I'd be happy to look at it for you.

I have an EE degree, but it's all CAN bus theses days...

I'll see if I can find a schematic :)...My guess is a sensor was disconnected (when they removed all the air suspension bits) causing the fault...

Why waste your time trying to hack the system, you're going to end up witha a can of worms if you mess up. Just get someone with STAR and code it for you. My installer did it for me when he install my coil overs.

That is what I asked originally or meant to imply....It sounds like it was programmed via STAR but is still throwing the error code. I am pretty positive Serge (he did not do the install) knows how to eliminate the error message, so probably best to start with him :)...

Yes it IS properly coded with STAR, I was told on E55 the error can be cleared but NOT on E63.

Your tech may want to speak with Peter's tech :)......

in case anyone is still curious this is what i have found as far a oem parts needed goes.

Attachment 378862

just realized the green line that says spring insulator is wrong, that is actually pointing to the rear spring height adjuster. the rear spring insulators are far left on top of the upper strut mounts and those prices listed are supposed retail cost. not what you could find online or wholesale

The rear spring insulator is only necessary if you desire to use the shims that come with it, to provide a little more clearance than the coilover's highest setting. The insulator itself is not utilized as the coilover's spring perch/height adjuster replaces that. The shims fit on top of the perch, as it would the insulator. A maximum of 3 shims is all that my installer recommended based on how the perch sits within the body well.

That being said, I think there's a problem with my shocks after installing the shims, which I hope it does not mean they're blown.

I am definitely interested in doing this swap. How much weight would this save too from the air matic suspension coming out? I would think quite a bit since all the hoses and pump and those struts would come out. I'm sure they prolly weigh a ton. Which H&R coilovers are people going with and KW coilovers too? Are there any others that people go with?

I would guess the weight savings is less than a 100lb (didn't get a chance to weigh everything). It's actually personal preference for coilovers and what your intent is. The H&Rs are basic coilovers with no adjustability in rebound/dampening; KWs have a wide range of adjusability for track purposes. Just be prepared for the drop to be lower than normal and that it may cause your camber/toe to be out of range of adjustability as well.

Isn't the height adjustable on the KW coilovers though? and also if I needed to then I'd get an adjustable camber kit.

Even saving 50 lbs from the swap would be amazing since I'm going to be going with lightweight 19's and 2 piece rotors and everything so if i can save like 100-150lbs by doing these swaps and taking stuff out of the trunk that isn't needed then I'd be happy.

The rims are 21lbs each for front and less than 22lbs each for the rears and the evosport 2 piece rotors will save me over 30lbs there alone so i should be over 60lbs saved on just rims and brakes.

coilovers are inherently height adjustable; the higher priced coilovers have dampening/rebound adjustments for the shock portion, which will affect the overall ride quality. KW and Bilstein are pretty reputable for their products.

Do a search on camber kits and you'll find that it's pretty limited on what's available for W211...but it's all depends on how far you're willing to go with correcting it.

Guys, I have a question for the peeps that had the conversion done.

Look at the picture of the "steel" lower control arm (the circled part):
https://mbworld.org/forums/members/t...m-02-33902.jpg
You see the part were the lower control arm mate with the chassis there is a slot. This is an issue, as the overlapping part is very small and will crack once 500+ ft.lb of torque is going through it.

Can you guys take a picture of your setup? How do you solve the issue? My guy is welding a couple washers to the arm ONCE aligned.

Are you saying your installer torqued the bolt down at 500 ft-lbs to cause it to crack? I'm not aware of it being a problem on mine. Could it be that the control arm just wasn't designed for the rigors of the wagon body?

No.

As you accelerate there are forces being applied to the mounting points of the lower control arm, pushing IN the control arm. There forces, thanks to our engines, can top 500+ ft.lbs of torque, potentially breaking the little tab (circled red) that holds the lower control arm in place. This is true of the Wagon and Sedan.

so the 500 ft-lbs that you're referring to is the torque from the AMG boosted engine? that's a different issue then. Being that mine is a non-AMG, I don't have the same torque specs, nor do the regular E-series sedans. I don't know what's typically standard on AMG suspensions...air springs or coils...but maybe the control arms are not meant for the rigors of the AMG. If coils were standard in some AMGs, then it shouldn't be a problem, as the arms should be designed to hold up. Could it be just a bad part? Have both sides failed?

Parts have NOT failed, but I do not want them to, so I am proactively trying to strengthen this potential weak point.

Can you take a pic of your undercarriage showing this mounting point, I'd like to see how it is attached on yours.

ah gotcha. like I said, if the AMG models had the option of non-air suspension, then I would think that the control arm has been designed to accommodate the torque of an AMG already. I haven't heard of anyone else having issues with it, as most of the people that have done the conversion have had AMGs. I'll try and get a photo, but I don't think it's going to be any different than what you have.

Here is a pic of the welded washer to prevent side to side motion of the lower control arm.

I don't see the slotted control arm being an issue regardless of any amount of engine torque... the control arm is is wedged between a bolt/washer and the inner sleeve of the control arm bushing, and isolated from the frame by the bushing itself. That weld has no integrity anyhow..I could break it with my bare hands.

nice job!

Hi guys,

Where should Coil Spring Shim (2113210084) be fitted?
Below or above 2113200026 ?

Thanks!

From today my car is with coils too :)
Dont see much difference :)
I'me really enjoying :)
:zoom:

I have a set of these KWv2's that I just pulled off my 07 E as I converted back to stock and sold the car. Looking for $1300, and I'm located in LA. Local buyers have preference. I put about 12K miles on them, and they were in 100% perfect working order when I pulled them. PM me if interested. I'll post them in the FS forum too, but this seemed like a good place to post them as well.

Anyone knows anyone in the Houston area who can work on my E500 conversion? And which one is better Arnott or Strutmasters? Have finally decided to save myself cash and headache by replacing the air suspension. Please help. Thanks.

I'd use Arnott. Look up M Power in Houston.

+1 I just used Arnott for our Denali XL - fast shipment and even got $50 back from our core deposit! :y:y

here's the guys I bought from
http://www.ebay.com/itm/REMANUFACTUR...item43b5a8659f

$494 for a reman strut, but you get $200 back when you return the bad one and they pay shipping!

May be true for Denalis, not for E55 AMGs. Let me know if you find out otherwise, I'd love to get some $$$ back on my cores.
but yeah, I like my Arnotts.

.

I am sorry I will off topic from KW coilover but still on the coilver topic in general.

I am about to order coilover kit for my car, but I am confused when I see the pics and I can not decide what to order.

For the rear suspension I see some of them you have to have the spring and shock seprated and you have to change the lower control arm to fit the spring in just like the KW here. A kit that I saw is:

http://www.octanemotorsports.com/03-...-p-137280.html

Another types I have seen that the spring and shock are together as one part. Anyone knows what is the difference? Will Both work? Attached picture of what I saw which comes from "KSport Kontrol Pro Coilovers". Reference link is:

http://www.octanemotorsports.com/200...-p-148177.html

or even this D2 where I also attached a picture of it:

http://www.octanemotorsports.com/03-...m-p-19662.html

Anyone can help here please :) ?

This look like the actual W211 kit:
http://www.octanemotorsports.com/ima...-Demo-copy.jpg

The 2 other looks like stock photo to other car's kits

I prefer BC Racing!

can anyone please tell me if the E55 and CLS 55 suspension is different from each other?

I used before front suspension from CLS to my E-klasse, so I tell, yes they are identical.

thank you

help needed coilovers swap for cls55
 

Can someone give me a part list an what coilovers I can get please

I don't know about the KW kit, but with the BC, it's the kit plus the rear lower control arm from the e350 and it's corresponding bolts.

Do you know where I can get the parts from e350 , I see d2 have a set of coilovers on ebay

I got it from Amazon. The w211 E350

autohausaz.com, parts.com...

This swap is easy. EBAY....BC coil over kit 900.00 EBAY E350 rear lower controll arms 50.00 to 80.00 dollars easy almost every day. Done . Pop them in and you are trouble free for years to come.

I need some part # because I don't know what I'm looking for I went on ebay an them other sites

BenzWorks has everything in stock

Thank you for the shout out MJ50, it's much appreciated.

Hi

I have a S211 2003 Avantgarde, I just made the air leveling suspensior conversion for the Arnott coil springs.

But im having some issues, according to Arnott instrutions it says to turn off the module that lies at the feet of the passenger, but doing that my bi-xenon doesn´t make the 4 leveling mods.

But if I plug the module back on, it makes all the 4 leveling setps, but doing that I have the error message saying that the wagon is down.

Has any one done the coil spring conversion on the wagon and if so, how did you reset the error.

(will be possible to disable the compressor)

You mean air compressor?
I'm not sure how i did it but i had same issue when I disabled some modules in SDS.
Anyway at the end i removed the relay of the compressor out.
And the auto leveling is working.

Yes the air compressor

When you say that the auto leveling is working, do you refer to the xenon leveling ?

You removed the the relay of the compressor did it apear error, and did you still disconet the module under passenger side, our just as said the the air compressor relay?

Hi,

yes. bi-xenon auto leveling.
i didnt remove any module under passenger side.
I just removed the relay and after that the compressor too (sold).
I also played with SDS modules settings but dont remember what exactly (it was few years ago) and i dont have any warning after that.

I have the Active Headlights Bi-Xenon on my S211, that dont work with the passenger module disconected like said on arnot instrutions, if I plug it on agian it works, but it makes apear the information of wagon with the up arrow.

My mecanic tryed to reset it with sam unit, but without success.

I may try and remove the relay, do you remember were is the compressor relay and what collor?

Dont remember where it was but here is the pic of it:
https://www.dropbox.com/s/d9ikhu9zzv...254-1.jpg?dl=0

But you NEED to do coding in SDS to disable warnings.
Look in the first post.
I suggest you to do it one by one and test it.
If i remember right, you should NOT change Airmatic suspension setting to Coil suspension setting in SDS.

I dont have airmatic suspension, I have rear air suspension only, And I cant change it to coil suspensio, because there is only that possibility for the cars to the wagons (S211) does not exist on the SDS :nix:

Hi mate,

even if it's only air suspension the modules should be listed in SDS.
Check carefully.

That relay location is the one inside the engine back that is located in the back towards the windshield?

Thanks for such a detailed post, and for sharing your knowledge. That E55 looks amazing! I just ordered a coil over kit for my w211 e500. Do you have any suggestions about where I can find the torque specs for all the parts?

Coilovers $?
 

what is the price tag at your shop. And in what city in California are you located?
