my car is dropped a lot, but not low enough to rub the fender, since i don't have a camber kit, the inner wall of tires are wearing out quick and damages the rims when i hit bumps. will i be able to roll on 205/40/z17 without a problem if i correct it? or would you recommend to use 205/45/z17 tires with strong side wall?

 

A Camber kit won't help you from bending your rims. The 45 profile might help a little bit, but bending your rims is due to shitty road conditions (i.e. potholls, tracks, etc). Just stay with some light weight 15's.

 

ride sucks on 17s... but cornering is fun!
