Tech help! Camber adjustment C63 W204 (rear rubbing issue)
Hey guys,
I have a '13 C63 AMG lowered on KW V3's DDC coilovers. I have upgraded my rear wheels from the multispokes OEM 19's (spec:19x9 ET54 w/ 255/30/19 conti tires) to 19's ZE40's (spec: 19x9.5 ET49 w/ 265/35/19 R888 tires).
I rub pretty bad on the rear right side whenever I turn left in normal driving conditions. I'm really looking to deal with this annoying issue because I purchased these wheels and tires for track purposes.
I looked into quality adjustable camber arms or bushings info on the forum, and there doesn't seem to have many options available. I found stuff on K-Mac kits (pricey) and SPC (I contacted SPC and they were not sure the kit was available for AMG's, they are going to get back to me on Tuesday).
Now, I know the 35 profile doesn't help, and was frustrated since I ordered 265/30 but realized they shipped me the wrong size after rubbing while test driving the car...
However, I don't rub on the rear left side while turning right.
Here are my rear values after alignment was done:
Camber: -2.5 left / -2.1 right (optimal from alignment software is between -2.3 and -1.5 and recommended is -1.9)
With an adjustable camber option, I could set it up to -2.5 instead of -2.1 and that would MAYBE solve the problem. However, my question would then become if that is too much negative camber, resulting in excessive unequal tire wear?
Have any of you guys experience with camber adjustement on this platform? What would you guys advise?
Thank you so much for your help!

The only way around this is to either roll/pull fenders or order tires with narrower side wall (ie not bulging) or mill the inside of the left rear wheel by 2-3mm to make it ET 51-52.
Reason is becoz of the way Mercedes subframe is set up. U will find that looking from the rear, your left side rear (ie Drivers side) stick out more than the right side, despite similar camber, tires and ET on both wheels.
I had similar issues with mine (in UK) when I bought ET40 wheels on the rear, the right side (drivers side) stick out more and was rubbing as mine was lowered on H&R springs.
I had to have the rear wheel milled by 3-4mm to solve this.
Hope this helps.

You have 4 options:
1. KMac - probably won't fix your problem, and you don't need any more camber in back
2. raise the height of the car - does it have to be that low
3. roll fenders - you can get about 10-15mm more clearance
4. new tires - obvious
Honestly, it doesn't help that you ordered wheels with totally wrong offsets - I wouldn't be surprised if you had an inch of clearance to the suspension on the inside. I mean, it could be the angle, but look at how far your rims are sticking out past the fender. I have 10" wide rims in back with 285/30 Dunlop r-comps (which run more like a 295) and it sits totally flush and I just rolled/pulled the fenders a bit and no problemo.
Good luck.

Thank you guys for your inputs!
I'll start by looking into how much more room I can get with rolling the fenders.
As for camber adjustment, I imagine values differ from wheels, tires and tracks, right? Are there any other options than K-Macs? How much negative camber can you have?

There is a metal tab in the fastening system between the bumper and quarter panel/fender joint. Looks like you are rubbing on it. You might be able to remove the inner fender liner and grind the metal tab down a little. That might give you some relief from the worst of the rubbing if not correct it all together.
KMAC's camber bushings will allow you to set your camber so that it is equal side to side and maybe lower the more negative side to within spec. I don't think you should increase your camber values past the -2.5*, you already have, to solve your rubbing issues. I think you are already maxed out on your rear cambers for street driving. You will likely just increase tire wear and maybe cause some handling issues.

You have 35 profile tires out back. That will be 1 main reason for your rubbing. Drop down to a 265/30/19 and then check back with us.
You can get adjustable camber arms for the W204. But before you play with any more negative camber, swap your tires to the correct size.
You rub on the passenger rear because that's where the battery is. Another 40-50 LBS of dead weight right over your wheel.

As was said before, by lowering you will get higher negative camber automatically. When I installed my Clubsport coilovers and went really low, I bought KMacs to LOWER my camber. Even on track, you do not really need more than 2-2.5 degrees in the rear (around 3.5 in the front). Your rims outer edge is 11 mm further out than stock and the 35 cross section does not help.
Milling a part of the inner section of the rim off is dangerous, as the amount of metal where the lugnuts hold the rim to the knuckle, gets thinner. Not a good idea at all, especially if you consider tracking the car.

I'll see how much space I can get with rolling the fenders and may buy or get my tires replaced with a 30 profile.

It seems for some reason rear camber is setup differently from the start by Mercedes on this car, lowering just makes it worse. Like I said, I will see how rolling the fenders help, and will look into having my tires replaced or either purchase a 30 tire profile. This situation sucks though.
BTW, the Clubsport must be awesome at the track, but how's your ride on the streets?
