[915M]

I used 734 19" wheels with M sport Brakes for 10000 miles.
There is about 3-5mm clearance so it was all good until I found a small problem with it.

Because BMW use wheel bolt system, unless you be really careful or use wheel alignment guide pins, when you take the wheel out or in, top part of Brake paint will chip. And I am pretty sure they will be chipped you put your car in for service. (Mine is chipped already.)

Thanks, that's good to know, and for being careful if you need to put the spare tire on.
