I bent a rim (3-piece forged HRE) and nearly destroyed one of my OEM CF splitters.
On my current M3, I'm going no bigger than 19"s and will not lower the car.
Ah man, this is the answer I was afraid of, but way better to hear now. Bummer on the bent HREs, that couldn't have been fun. I've got a three piece DPE wheels that I'm not looking to wreck either– might have to give another thought to selling them and going with my 18" apex for city duty. Atleast south park is a quick jump to the freeway and getting out of that mess
Thanks for the insights!
