Most people tend to come to me for fitment questions...but I don't know much when it comes to stock camber...
Camber is a -1.0 F (and I believe the same in the rear).
Couldn't get more out unfortunately (didn't want to pull pins)
Can one fit 18x9.5 et 22 265/35/18 18x10.5 et20 285/35/18 RS3s on a stock 100% suspension E93 M3 with only -1 camber
From my own experience, I would say yes it will fit.
I know of an individual who fit 18x10.5 et20 285/35/18 (I believe NT05s) in the front on stock suspension with stock alignment (also an e93 M3).
Any input would be greatly appreciated
