need more negative front CAMBER

have 06 c350 MT, lowered car with kw v2 . i added dunlop star spec tires and car sticks like glue on east tenn mountain roads, a real blast, only problem is outter shoulder is worn off while rest of tire has about 30% tread left. any suggestions? im told that coil overs have no camber adjustment , but i think i remember reading somewhere that a thick washer can be added somewhere to accompish adding more negative camber. thanx, mike

ive read the thread but am confused, ive been told that camber cant be adjusted w a coilover (c/o), i also remember hearing that the kmac camber plates are cr#p, my rear camber seems fine, im only concerned about getting some more negative camber on the FRONT ONLY as the outer shoulders of the front tires are worn while the rest of the tire has 30% tread left, thnx, mike

Variable camber depending on wheel turn. At straight ahead it is slightly negative standard.

As e1000 says you can increase negative camber by location of 3 position bolts in the camber bushes, thereby going out of spec.

Maybe im crazy, but maybe the outter lips of your tires are wearing faster than the inner because you have excessively negative toe and camber might not be your issue?

You need only 2 fluted camber bolts to replace the standard ones so you can move from centre position in the bushes. Standard caster & toe & go as far as you can with camber. Max 4 if it pulls the caster.

Tru - you could be spot on but I think aggressive driving

Frank - I think you have a particularly well set up car - When I've looked at your pics I can see the tyre wear is even.

Im glad I'm not that crazy.

I had around -2 camber (or more) on all four corners for 35k+ miles on my tires... Only my rears have worn unevenly and that was on the inner side. I drive it hard and all, but I have a hard time imagining how my front tire wear could be more on the outside.

Additionally, the hardware for all of the adjustability up front is not easy to install. IIRC, it requires a hydraulic press?

mlg: maybe have your alignment checked first! Check out Firestone - they have a 140 dollar life time alignment deal. Nationwide coverage too. You pay up front and you can go back as much as you want.

Good luck

You are certainly not crazy Tru - As for hardware. You would only have to get a press if you need to change the bushes. If they are OK all you need are the bolts.

My car with dead stock set up wears the outer front edge of the front tyres slightly more than inside.

The best thing to do is to get the bolts & then go along for your wheel alignment. They will pop the bolts in while they are doing the alignment then you have the adjustability. My alignment shop even supplied the genuine Merc bolts. They carry them in stock for this reason. Every alignment shop in South Africa has Merc castor & camber bolts.

thanx for Firestone idea, sounds inviting.
any suggs for goal 1) camber---Maybe -2 degrees like trutang , 2) caster , and 3) toe for my car for aggressive street driving?? thanx again, mike

It’s ghetto, but the “washer mod” has been used successfully by several respected members (smgC32, Zeppelin, MRAMG1, CynCarvin32) to gain additional negative camber in the front.

If you’re unable to achieve relatively even front tire pyrometer readings or wear during spirited driving after having fit MB’s eccentric bolts, inserting a washer between the two lower strut bolt mounts and the steering knuckle will provide an additional ~-3/4 degree. It is akin to adding alignment shims to an A-arm suspension.

Just today dropped another $1050 on a set of Michelins; I’d rather they last as long as possible.

John, you take your car on track - yes? I don't think most road people do comparative pyrometer readings across the tread

Did you get PS2s?
