I hear you on fitting smaller wheels. Would have been curious to hear about track performance with the 6/4 pot factory setup... BMW finally decided to kit the cars with monoblock calipers, they had fitted cars with such crap brakes for so long. Brake fade was a big issue on M cars with crappy floating calipers for such a long time. Not so much any more, at least from recent reviews. Still, $6k is a huge chunk of change for this upgrade. Car is looking good!
