I'm getting +43 18x7.5" w/ 225/40-18 rubber on Tuesday. If I actually do get to lower my car, the one thing that I am not sure about is:

How much can I correct rear camber without rubbing?

I think I'll save the money on the rear camber kit, unless I have proof that it can be done w/o rubbing.

Jschmid, do you have bad rear tire wear? I am going for the same H&R Sport drop as you. Also, does your buddy have rear camber correction?
