I thought about that but when i loooked at the photo of the bottom spring, the last coil seems to be the only coil thats holding the whole spring up. Its eithe ill gamble and cut from the top and see how i can somehow rotate the too pads so it would sit properly with the cut spring or change to coilovers and sell my H&Rs or leave everything alone.

The other thing to worry about is how much preload these springs require. If cutting the spring reduces the preload amount too much your spring could jog around seating improperly assuming your suspension fully extends like say during a car chase on hilly San Francisco roads.

Hahaha! You're right on the money there my friend! I guess ill just wait and see until i change my rotors and pads so i can just do it all in one go if i still decide on cutting them. .

No worries, will do. But can you tell me how to attach a photo as an actual photo and not as a small attachment? Sorry but everytime i try to include photos its always coming out as a small attachment that viewers have to click just to see the actual pic. Thanks mate!

I usually use Photobucket and there's an option to copy the image code. Typically starts and ends like
[ IMG ] ...[ /IMG ]. Just copy and paste that in your text and it should show up on the post preview if you use the "Go Advanced" reply option.

Thanks for that. Im sorry but I dont have new pics at the moment and all the photos I here, I have the front wheels turned a bit. but if you look close, you can probably tell that there is around an inch gap from the rubber to the wheel well at the front.

I like the look of a decent meaty sidewall. I feel 18s are the highest I can personally live with and maybe 19s depending on the wheel design. I'm really hoping to find some stock 18" 08~09 e350 sport package wheels. Really like how that look on a black e350 even though I know they'll be a pain to clean.

^ love those rims as well. If I was gonna change the look on my car I will go for those and if only they come in at least 19s, that'll be perfect for me.

You don't have to cut the coil, you can simply move the base at the bottom of the spring (shock has circumference channels and clip that hold the base and can be moved up or down) that holds it. Nothing wrong with H&R springs they work better than Eibach, you can see my car lowered on H&R and Bilsteins here:

I just put the ring in lowest position possible but i still can drop 3mm because i have plate machined to center the spring upfront.

I still have the stock shocks so Im not sure if thats applicable. but if it does, that will be the best solution i reckon. can you confirm. cheers mate!

It is applicable for OEM too, here is the official MB document for front strut repair. It is PITA to get it back together after disassembling it but works.

beejaypunsalan, using the adjustable ring on the OEM strut assy shock is an effective method to raise or lower the ride height (by increasing or decreasing preload on the spring), but keep in mind it was designed to work optimally for a specific spring design (OEM). Since you're using aftermarket springs on OEM strut assy shocks, it's possible the combination won't harmonize well when adjusting the ring height lower or higher. Reason I point this out is that I've seen H&R offer lowering springs coupled with a spring specific aftermarket shock that had adjustable ring heights. isstay, how long have you used the H&R + Bilstein combo and are you noticing any degradation in your ride? If all is good I'd be interested in running the same set-up one of these days. Your drop looks nice.

Isstay: thanks for this info mate! Very usefull if i decide to go this route.
About Dragona5h question, im interested to know as well.
Dragona5h: cheers mate! Ill definitely consider all the consequences before i decide what to do with my car.

Ring is used by MB to adjust cars height, just like the rubber shims on the back of the car. It is true that moving the base down will change your spring rate, but this will be less noticeable with H&R/Eibach than the OEM. Those are already stiffer and shorter thus allowing bigger spring extension will improve ride quality (less harshness). I've been running this setup since spring in combo with 17 inch summer tires and only change in ride quality I've noticed was in first few weeks until the suspension components settled down. Since then there is no change - ride is controlled (almost no movement front to back when accelerating and breaking and small body roll when cornering in comparison with OEM setup). I do fill almost all road imperfections, but in controlled manner. Passing and cornering difference is like day and night, actually for the first few days after the upgrade I had the filling like my car is running on rails (slight steering wheel movement and car goes in that direction), even switching back to 16 inch wheels with winter tires did not affect the handling too much (way more control than OEM setup). Some one who runs B6 with H&R probably will have different experience since those are little bit longer than B8, thus more room for spring extension/compression.

Springs, shocks (hard to come up with them since BilsteinUSA does not list them for CDI models, thus I have to go through BilsteinDE to find part numbers and source them from online retailers for diferent MB models - like CLS) alignment bolts and alignment - no more than 750$. Alignment is in specs, except for rear right corner (like 0.5 over the limit) but is on the end of the allowed tolerance with even tire wear. I do have alignment bolts for the rear end made but I am not putting them until I'm ready to install Eibach sway bars.

No, those are only available on coil over setup from Bilstein, which I do not like from reliable stand point (not like i will start messing with them once they are set - height wise). You can get Koni shocks with FSD and they adjust itself automatically but they are costly option and I heart that they do not last even so they have life time warranty it is not worth the hassle to change them every few years. Bilstein also heas life time warranty on B6 and B8.

Good info. Thank you. H&R + Bilstein shocks with height adjustment. I think we have a solution to the OP.
