Depending on the tire you choose, the rear may require a fender roll to alleviate tire rubbing onto the fender as extreme performance tires tend to run wider than most street tires.
You can get the 18x9.0" ET42 to work with your 335i as well, but it does not have the concave face that you want, and would require a spacer in the front.
Thanks for the quick reply and PM, David!
If I ran 255/40 street tires, would I need to roll the rear fender? Car is pre-LCI.
