I just got back from tweaking the rear cambers out to the max on my 20's. I also tried to compensate the "bow out" with tweaking the toe in the rear too. I am a little pleased, but there is still more room for an adjustment. The inner part of the tires still have more contact with the ground than the outside does. About 1" - 1 1/2". What is everyone doing to try to get these back in a bit? Only harmful thing it is doing is going to wear out $1,400.00 dollar tires quicker than I would like. =/ What has everyone else done with 20's? Probably some of them do not even pay attention to this I assume? For the most part it is doing this as a result of the width of the rear. Right now it is set at (-1.3), camber. Help or any suggestion would be greatly appreciated.

Your camber problem should have nothing to do with 20s. I have 20s and my camber problem was created by lowering the car with springs.This caused mainly wear to the front tires backs are not bad.I have changed to full coil overs and raised the car closer to factory ride high to give more ground cleance for new body kit.

 

consider yourself lucky...i am lowered 1" in the rear, and the best i can get is -2.5 degrees. -1.3 degrees is about stock spec, so you are doing good.

 

I have 20x10.5 and the dealership re-aligned my 04 coupe. They said it was 3 degrees out of alignment! This is a brand new car that has never had any suspension mods. My buddy also had factory camber issues with his Z. I think there is variances in the building of these cars. Have you brought it to the dealership?

 

I had another alignment shop that some of my friends work at do the alignment. ALOT cheaper. The dealership would charge me out the yang.

You are at spec.. I would do nothing. I'm at 1.8 and I can't go lower cause my Toe will get wacked. I have over 10k miles on my 20's and the tire wear looks fine. If you are worried about tire wear, worry about your front's. It cost a grip to get those back to spec.
