When it comes to brakes, 18s can house brake discs up to 360mm diameter (14 inches +). Really fine, sophisticated brakes of that diameter are capable of stopping anything, forever.

The question is why BMW had to make these M3-specific 18s so ugly.
I agree that tje 18's are fugly. In the e46 M3 did BMW change the wheel design at some point or were the same wheels offered throughout the the entire model life
