I haven't been on the forumn in quite a while but I seem to remember someone else talking about a part to help adjust out negative camber. I have a 04 Roadster with 20's.
F - 245/35ZR20
R - 275/30ZR20
Anyway the rear wheels have a pretty serious negative camber and I am getting uneven inner wheel wear - this would make sense.
I don't do any road coursing and certainly couldn't afford to do so with the P ZERo NERO' sthat are on it.

Does anyone know of a way to adjust out the negative camber, I seem to remember there was some add on brackets necessary to make it happen?

 

SPC Rear Camber/Toe kit.

 

Dutchy - thanks fo rthe quick reply. Did you have to install these?

 

I got my local tuner shop to install them. It requires elongating (drilling) the toe bolt area.

 

I have the SPC kit as well, but do a search on camber. There are several rear camber kits out there and you'll find lots of discussion on front and rear camber.

 

I'm still waiting on Cusco front adjustable A arm and SPL rear camber/toe kit. I'm putting these on on saturday.
