For the front you may need some type of front camber plates for those tires with ET40 front offset. Otherwise if you hit the track and drive the car with full opposite lock, I guess the front tire will touch the fender.
Thanks for the input guys.

The wheels are 18x8.5 ET45 APEX EC7s. I have Koni yellows, Dinan camber plates, and M3 control arms (-2.0* of camber overall). The strut clearance in front already seemed marginal, even with the stock 262s (17x7 ET47) - my last track day I saw the inside of my drivers tire chewed up a bit from the strut perch.

Front fender clearance looks good at the top for now, it looks a little tight in the front, but I'll hopefully have some time this weekend to put the car up and check things.
