I don't understand what the KMAC kit does that the factory rear alignment concentrics don't do. I was able to get my rear camber to -1.4 with the factory concentric, and that's after lowering it. Or are there some years that didn't use a concentric in the back?

I'm assuming they all must have concentric adjustments in the rear, but the factory setup does not provide enough positive camber adjustment to compensate for the current drop. I am hoping the KMACs will provide the additional adjustment to bring the alignment back to spec.

the rear has concentric bolts BUT...my rear is dropped around 2 inches so my camber is perty bad. The KMAC kit puts a concentric bolt on the TOP in addition to your bottom adjustable bolt so you can get more camber by pushing the top of your tire further out.

Lucky my guys got mine to -01.77 degrees and said it would go no more, may try another garage or try one of the kits if they will help?anyone know?car has sports suspension but not been lowered etc
