This one of the things that amazes me about the E90. It has just one big piston in the front caliper, nothing fancy mind you, and it stops within a few feet of the same distance at 70MPH of many supercars. Granted, a supercar's brakes will probably last longer without fade under track use, but still, it's damned impressive.
