Will adjustable rear Camber Kit fix my rear tires from waring on the inside? Also know as Upper Control Arm.

 

Yes, I did this on mine and I believe I set them to about -1.5 degrees (this was 4 years ago so my memory may be spotty, do some research and you will find the right spec, I think swedespeed is where I found mine). Tire wear hasn't been an issue since.
