M-Performance brakes are 370 front 345 rear. I'm think the M-sport rotors are smaller but the caliper is the same but i'm not sure.

EDIT, quickly glanced through that thread and the only difference between the M-Perf and M-Sport is the caliper color and rotors being dimpled.
M-Perf and M-Sport rotor diameter is the same
