I may have to fiddle with this a bit.

My car is lowered about an inch or so, so I have a bit more rear camber than stock. My stock 15" wheels with 205/60's are fine, but last year when I was running around with my Azenis on the back, on 16x7.5" rims, I did not get full tread contact with the ground--at least not in a straight line. The outer inch or so of tread was up in the air. It worked OK for autocross, but did make me a little nervous about tire wear on the street.

The camber in front is not so severe. Still, I ran 31 psi (as on the placard) on the street. I can't remember what I used for autocross--but it was a wet day so I left things pretty soft.
