I installed my camber kits recently and took it to get aligned and the guy told me that he wouldn't be able to get it back to 0. I've seen some people push 1.0 and are fine so i told him that. Then he told me after 20 mins that with my camber kit he wouldn't be able to adjust to 1.0 either.

I bought the anchor bolt camber kits. SPC performace ones. But my question is if i also buy a ball joint camber kit will i be able to align my car better? would it improve my tire life? would it even matter?
