Hello MBWorld C63 AMG owners,

The day has finally come. I was able to work out a deal with HMS Tuning Germany and my freight forwarding agent to get the absolute best price shipped from HMS Tuning direct to my warehouse in Niles, IL. Once items are here, local pick up is welcome and items will be shipped via UPS Ground and will be charged actual shipping cost. My goal was to get at least 5 people interested including myself to get these into the US without the hassle of US Customs, etc and bringing down the cost of air freighting them in without paying $3500 or more landed, minimize the time for the products being stuck at customs.

HMS does not have any fenders in stock, they built individually to order. The lead time on the fenders is 6-8 weeks or more for the entire order. If there are more than 7 people interested, I could talk to HMS about doing more of a volume discount and add them to another shipment, but cannot process it until there is another 7 sets order and will be considered a 2nd shipment/order.

As you know factory C63 sedan fenders allow up to 10.5j width but keeping the offset around +45 ~ +55. The most common set up is running a 9.5j +50 or higher to accommodate 265/275/285's depending on ride height.

The HMS fenders are approximately 40-45mm (1.75 in) larger than factory C63 sedan rear fenders. These fenders are perfect for those who are force inducted (Supercharged/Nitrous etc) or just wanting a larger width wheel/tire.

The HMS tuning fenders are hand laid fiberglass (FRP). They consist of 8 pieces total.

(#1 Main flare x 2pc)
(#2 Flare with door card x2)
(#3 Flare with rear bumper card) and finally the (side skirt card x2).

plus Optional* OEM Black Series fender liner L/R.


Test fit mounted on a C63 Sedan:





HMS Wide fender kit FRP (Total - 8 pc)





HMS Wide fender kit sideskirt/rear bumper card width FRP (inches)





Installed and painted:








Installation will be the buyers responsibility. Since these are technically "bolt on" flares with the factory metal that needs to be trimmed/rear bumper bracket modified. Please be aware of the install costs and my advice is to you is to shop around body/race shops that have done this before and aren't going to charge you like $3,000 to bolt on, cut and paint these fenders.


MBWorld GROUP BUY Price is: $2,100 USD*

(This includes a set of FRP HMS fenders, OE Black Series liners, Air Freight, Transportation costs which includes Freight pick up from HMS Tuning to Hamburg airport), Duty & Tax and documentation charges)

You are free to pick them up locally for $2,100* or have them shipped to your door step via UPS Ground, charged commercial pricing for actual shipping costs.

Once 7 set minimum goal has been set or more. I will wire the amount to HMS Tuning and production will start immediately after the full deposit's have been paid. Maximum order of 7 sets is needed per this shipment.

**If there are more than 7 sets on this group buy. That will be considered a 2nd order and will not be able process until that order reaches 6-7 sets

I hope I was thorough enough with this and it was a pain in the *** but totally worth it.
If you have any questions please ask here! Now let's get 5 sets or more going!

MY2012+ Facelift sedan:

roadtalontsi

alright throw me on the list. I cant fight the power of the dark side.

BLKROKT

I'm pretty tempted by this as well.... Do they make these for the coupe, or will I have to get the sedan extensions and make them work?

mthis

Great Price. it cost me alotttt more for 1 kit alone. great job setting this up .

Phil Chow

Will speak with my shop today and get a quote on installation first. But, I'm interested.

rickclass

So these are not DIY? I.E use 3M and some poly urethane? do they have to be cut into the existing fender?

durranic

oooo i cant wait!!

gmaschine

Dark side is much cooler anyways.

I have never seen them on a coupe. I've been asking my friends, service managers and sales reps at my local MB dealership and I still don't have a clear answer on if the coupe/sedan flare dimensions are the same. I believe they are or very, very close.

Having a body shop doing a retrofit shouldn't be too difficult as the general shape is there. You will have to fuse/mold the door card to the main flare and do some trimming.

No problem. I wish the timing was right so you could have been on this GB, but much respect for trying to import them in by yourself.

Sounds great. Let me know what your local body shops are quoting.

It is more of an advanced job. I would recommend a good body shop, but if you have some body shop / race car prep buddies willing to help out, it could be done. The video posted above gives you a general idea of where and what to trim.

You have to measure and cut the factory metal underneath, no cutting of the rear door. HMS Tuning recommends strong automotive glue/adhesive. Technically they can bolt on for looks but you will have to run "sunk" wheels and will gain no additional clearance for wider wheels/tires.


Me too! I keep watching the HMS-700 video and it keeps me motivated. (0:55 UGHHHHHHHHH)

honestly i contacted them myself about two week ago and its a huge price difference i do thank you for making this happen! im just worried about the paint work that will be done, i know they will blend it but still sketcy with the color match.. yes that video is awesome!!

gmaschine

Buying bulk and shipping everything all together makes a huge difference. The reason why the landed cost as an individual is so much is customs and HMS Tuning not being able to do door to door delivery.

Once the item arrives to US customs as an individual, US Customs will charge full Duty/Import Tax and they charge an absurd amount for inspection fee's/X rays. (The X ray alone on a 40' ft container is $1500-$3000) it is less on a single pallet but once that has been done, they charge you the full shipping to your doorstep. Hence why it costs $3000-$3500 landed.

For paint matching. As long as you shop around and find a good body shop. They should be able to match it very well. The best way to do this is not to ask for the paint color itself but to find your exact paint code and have the body shop paint it using "German" paint.

Phil Chow

Thanks for putting this together Ernst V Bauer.

That being said, is it possible to somehow throw on wheel fitments that would work with these fenders in the rear?

I'll have to order a set of wheels too, so, would need to get that sorted out also. Any way that HMS can confirm what they recommend with their wider overfenders?

gmaschine

HMS Tuning recommends:

19 x 8.5 +35 - 255/35/19 which is aggressive for the front.
You can opt. to go with a 8.5 +40 / +45 and keep the tire at 245 to be safe. Depending on the ride height.

19 x 10 +25 - 285/30/19 which is a perfect match with the rear fenders.

You can play around with wider wheels, bigger tires depending on the offset.
http://www.willtheyfit.com/

Since these fenders are FRP (bow to 50mm+/shave), you get away with slightly more aggressive set up's versus metal widened fenders.

https://www.hms-tuning.de/en/product...-packages/c63/

Phil Chow

I thought we established those specs are for their older fenders, that were only 30MM Wider?

These ones are 45 - 50MM wider right?

The 19x10 +25 is only 25MM more aggressive than what we run stock-body.

gmaschine

Yes, they are 40-45mm.

The HMS Jade-R wheels are meant for the wide body upgrade. There is also the difference of being completely flush in the rear with tiny amount of poke and "safe" flush where the tire is very equal to the fender line. But this all depends on the width of the wheel, slight amount of stretch, tire sizing and brand of tires being used.

Take the most aggressive set up on your stock fenders and you have 45mm more to play around with. That part is up to the user, I am only posting what HMS recommends what they run on their demo car.

Phil Chow

Undestood. Must've misread the other thread. Thought you said that those were the 30MM older version which runs the Jade R Wheels.

There must be a big difference, since, well, somebody run 20x12.5 with 325s? Compared to the recommended 19x10 +25 with 285s?

gmaschine

Sorry for the confusion.

The first production models were 30mm, I think Dad's C63 bought the first run. HMS fixed this and made them wider to 40-45mm.

So 40-45mm is the current production size of the fenders as is.

The 20 x 12.5 - 325 set up was done by Wolfgang Domanig's C63-RS.
He widened the HMS fenders to like 75mm+! I posted some pictures in the other thread.
I can ask HMS what they recommend if you want to run tire sizes over 295.

BLKROKT

I'm a little confused. Are they 40 or 45 mm? That's not an insignificant variance. And if these are all hand-made to order, why not 50mm? Or 60mm? Are there any options, or is it just going to be whatever they decide to make, somewhere in the 40-45mm range?

Phil Chow

Ahh, that makes much more sense!

Personally, i'd look into a wider wheel to be honest.

Well, from my calculations:

19x10 +25 is what they recommend.

That is the same as running:

19x10.5 +31
19x11 +37
19x11.5 +43
19x12 +49

In terms of OUTER CLEARANCE

Now, assuming that 19x10 +52 is the closest we can get to the inner strut without rubbing, that means:

19x10.5 +31 (+15MM Inner Clearance)
19x11 +37 (+2MM Inner Clearance)
19x11.5 +43 (-10MM Inner Clearance)
19x12 +49 (-22MM Inner Clearance)

So, it looks like we could potentially run:

19x10 +25
19x10.5 +31
19x11 +37

All of these wheels fit 100% the same in terms of OUTER CLEARANCE, with a slight variation on inner clearance.

Problem is though, a 315/25/19 or 325/25/19 tire does NOT exist according to my Google Searches and Tire Rack Searches. Which, brings another issue in hand, what tire do you run with a 19x10.5 or a 19x11?

marioflex

Maybe P Zero Trofeo325/30-19

Phil Chow

That tire would be way too tall.

The largest I would run on a 30 Series is a 285/30/19. Even that is significantly taller than OEM already.

Going up to a 295/30, 305/30, 315/30, 325/30, would be ridiculously tall.

gmaschine

It is what HMS decides to make. I think if they we're to build by customer's custom specs it would take forever and may have some issues with all the other flare components fitting with one another.

I believe that the 5mm tolerance difference is there for the inner lip/flange (which you see on factory fenders) for structural rigidity. Most people shave these to gain additional width.

Mthis can you confirm if these come with an inner lip?
(Example: You can see the inner lip/flange on a different brand/car type rear fender. It's about 5-10mm.




That seems about right. Sorry for the confusion again but the Dominig C63 runs 20's not 19's. Hence the lack of certain tire sizes/brands.

Example: Michelin PSS 285/295 - 19 x 10
Example: Michelin PSS 295/305 - 19 x 10.5
Example: Michelin PSS 305/325 - 19 x 11

But matching the front tire size, within 5% rolling diameter is important for correct speedometer readings, handling etc.

durranic

gosh right now im running stretched 285/25/20 on 10.5s for my rears with no rub. im at least trying to get to 305s or 315s for more rubber on the floor with these fenders..

solekeeper

there is no such thing as "german paint"

the correct way to match a color is to locate code, and choose the best variance to the color. obviously in the end the painter is the deciding factor. his technique needs to be right for the color to layout correctly.
