Please consider that the six pot Brembos are not suited for track use, while the one piston M3 brakes at least hold up okay. BMW isn't known for good track brakes, but either way, number of pistons isn't a good indicator of ultimate performance. Proper cooling ducting to the brakes, pad material and overall system capacity means a lot more than piston count. Simply look at the track forums to see multiple examples of the poor quality of the 135i brakes, or look at other forums to see how poorly Brembo calipers on 370z's, Evo's and STi's fare under track usage.
