With an extra 4mm offset, that should just about bring the wheel back in to the standard issue AMG 8"/ET31 clearance - not sure how much you'll have on the inside. Having said that, my 8"AMGs rubbed once (and pushed out the fender

!) when I swung full-lock a little too fast (and I'm already using 225's instead of the recommended 235's).
My $0.02 worth.
