I am on 235/35/19 up front, 265/30/19 in the back. Offsets 35 front, 30 back.

Most cases I've heard from were issues on the front with regards to spoke clearance and not the rear. Although I think effective offset on the rear of our cars are typically lower than ET30 (mine is ET21 and I run the same tire size on 9.5" wheels).
For front fitment, this is a good reference chart, though it's made for the E46M (similar fitments) and specific to Apex wheels. You'll notice that for RR 911 brakes, the ARC-8 doesn't fit without a spacer but the same spec EC-7 does. It all comes down to spoke clearance.
