** HMS TUNING WIDE FENDER KIT GROUP BUY **




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.

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.

All of our factory fasteners work. You'll see once you get in there.
Here are a couple of pics from my journal thread.


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.

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 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.
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.

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:
So you may use the existing clips and screws beside one or two of them which are in different locations,
what would not be a problem as you have got about 10 mount points total for the liner.
The only thing would be at the front area of the liners in driving direction.
There the factory Black Series vehicle is even more wide and you might have to cut the liners a bit with a knife to fit to the wheelhouse.

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

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

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.

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.




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.
