I am planning to call the body shop tomorrow. I think by the looks of the fit I will be moulding it to the body as well. I will not know for sure until I get it to the shop, do a test fit and discuss it with the shop owner. I think I prefer to mould it in to the body and that will be my intention.

Thanks for the measurements Mort.

I was able to check the OEM Black Series liners fitment on the rear today.

It's similar in shape and wider but you will need to devise new mounting points and some trimming such as AMG3.2's example. They are part of the same #A 204 parts index but the Black Series has different fasterners and mounting points. I just wanted to clarify that.

I'm relieved that there's an OE part that will work with aftermarket rear fenders . There isn't a wide fender kit out there in the market that has one, except the W204 and very few other cars.

You wouldn't happen to know the part number for those fasteners would you? I'll be test fitting soon and I also have a wheel fitment tool to get an accurate measurement. So we'll see what I come up with and I'll post my findings.

If you could give the measurement it woul be great !! I really don't want to work on the fenders until my wheels are ready or in process.

Anyone else bite the bullet?

Also? Did folks settle on tire size? Looks like MPSS in 255/35x19 and 295/30x19 are a good match, size wise. Can't see running 20's where I live. Would love some more tire up front, but looking hard to squeeze it in there.

It's not that you need the new fasters to make it work. It's that literally, the BS liner is just shapes a bit differently and needs to be trimmed to fit. New holes need to be drilled as well for the chassis screw like things to be able to poke through the liner.

All of our factory fasteners work. You'll see once you get in there.

Here are a couple of pics from my journal thread.





Check out my build thread for some reference (link in signature). I could post here again, but not really trying to litter the forums with the same stuff. I test fitted a 19x10 +51 with a 40mm spacer and I think I'm tentatively happy with that fitment. I'd go for something that equates to that offset and then use spacers from there to fine tune.

The danger here is that we're dealing with fiberglass and rubbing is about the worst thing we could do to it -- especially for those that have or will plan to mold them to the body.

Ah ok! Thanks for the detail. I should have mine in the shop in the next month or so. I'm still waiting on my BS front end to come in before I send it to the shop.

I wish I could post the wheel well of a C63 Black Series, unless someone can help but 3.2 is correct. The shape is similar but the liners have different mounting points on the fender side of the Black Series. You will have to get a bit creative and create new holes for mounting points.

Thanks for the pics.

The 10j +11 looks good and that seems the be the target width offset of a 10" wide wheel.

Fiberglass is actually more forgiving than metal since it flexes more and won't destroy a chunk of tire when it lets go. I would be worried about front fender fiberglass fenders when you are low or turning lock to lock. The rears will flex on extreme situations and you have the compression of the rear suspension to help camber in. Fiberglass literally turns into dust.

Tom,

That's a good combination for anyone running these fenders. But it all depends on the front width - 8.5, 9 and front ride height. I know the MPSS runs wide so please consider that and you can shorten the sidewall a bit by going 9j in the front. 20's seem ridiculous but they don't look too big if your doing multi piece wheels with a stepped lip (since they use a 19" face) and you will have more options to run bigger tires and less sidewall clearance issues.

3/21 Update concerning production time and liner fitment
Production time for the 2ND Group Buy will take 6 weeks from start to finish. Shipping and processing around 2 weeks. So once 100% payment from 7 orders is made, it will roughly be around 8 weeks.

I was able to get an HMS technician to go over some issue or concerns regarding the Black Series O/E liners:

SECOND GROUP BUY for HMS Fenders for Sedan/Coupe
HMS Coupe/Sedan fenders, OEM Black Series liners New GB price $2504

1) Dr Karns - 2012+ Coupe (DEPOSIT PAID)
2) Computertom - 2009 Sedan (DEPOSIT PAID)
3) Negrette10 - 2011 Sedan (DEPOSIT PAID)

4) Phil Chow - 2009 Sedan
5) Gzim355 - 2012+ Coupe
6) RedNiteJ - 2010 Sedam
7) MAGASC63 - 2009 Sedan
8) JC63AMG - 2012+ Coupe

(We have 3 orders paid and 5 people interested. If you would like to make a deposit, feel free to PM to lock it down. Once all deposits are received, production will start immediately. If for some reason all 7 cannot be met, a full refund will be given. All fenders will come with OEM Black Series liners (L/R) sides included with the price. When the fenders arrive, you will have to pay for domestic shipping from me to you)

I am thinking about putting a deadline on this Group Buy soon but it is still undetermined. Also, this will most likely be the last Group Buy for real.

So lets get on board before it leaves for good!

Another recent example done in NL.

This C63 has OZ Racing Ultraleggara HLT in 19x8.5 +38 19x10 +25 with 235/245? and 295's. They are another option for anyone who wants to run a strong track wheel that meets the fender clearance spec. They are also frequently run on HMS cars.

So I just took measurements and came up with 20x11.5 -32 offset. Am I crazy? Backspacing came in at 178mm, frontspacing came in at 144mm.


Rear


BS Series front. I'd like to fit a 20x10 but I'm not sure it'll fit.

I've honestly been wondering how these might look with a staggered 19F and 20R setup, since that rear opening is so huge. Anyone thinking something like this?

Any other orders coming? Come of folks! Let's get this rolling so we can enjoy some of the summer with some fat bottoms!

-Tom

From my calculations, that's totally doable. Please do your own math to double check but the pics on my journal thread show 19x10 +21, 275/30/19.

According to my calculations, your proposed setup of 20x11.5 +32 should be 8mm more aggressive that what I'm running with my makeshift setup.

Again, from the perspective totally doable.

Awesome. I was planning on running a super concave wheel and that's how I came to a negative offset. Maybe I'm calculating things incorrectly from that perspective.

Yeah this'll be positive offset for sure.

n/a

Yeah for sure. You see where it say's it'll extend another 118mm? Equating that to inches means that setup will poke 4.6 inches more than now. Our fenders are not adding that much room lol

+32 fitment is correct

19/20 can be done. I've ran quite a bit of wheel stagger set up just not in those sizes. It looks best when the car is real low.

There is alot of interest but there are quite a bit of flakers. It's not an easy commitment by any means but the gains are worth the effort.

I will set a 1 month cap from today. April 30th will be the deadline.We only need 4 more orders needed for it to happen again.



+32 will work 100%.

Since you are on air you can go more aggressive, once you figure out how much clearance you gain from completely "airing out" before the chassis hits.

Look at how freakin amazing those fenders look. Come on people! Let's do this thing!

Here is some info and pics of the rear to set up a framework. I installed my Axioms with a 50mm spacer to get some measurements and ideas.

Axiom FLY M1 - 19x10 ET +52 with a 50mm spacer makes it an effective ET +2

Fender arch is sitting on the top of the tire.

Camber - 2* 15'

Flare lip to floor 26" (1/4" higher than a previous measurement with car at current ride height) and the car has about 1/4" before it is lowered to proper ride height (due to fender lip sitting on tire). Tire is a 265/30/19 MPSS and on a 10" wheel is stretched a bit but it will tuck.

Straight edge across wheel lips is perfectly flush with outer edge of flare ( flare tapers in just a little down the face of the lip = 2mm).

Car is on KW V3 at their lowest setting in the rear. I have KMAC camber/caster plates on the front and camber caster bushings if needed. I have KMAC camber bushings installed in the rear.

ooooof. That +50mm's looks pretty aggressive to me. Almost to the point of potentially knocking the fenders when bottoming out, no?

The stretch on a 265 on a 10" rim should tuck it in nicely. Might need a touch more negative camber?

I am hoping for something close to that for fitment. I am hoping to get the lip of the wheel close to the outer edge of the fender and for a tire with just enough stretch to tuck. Might even poke it out a little more and keep the ride height up just a tad.
