I will ask him if I can add any of the M Performance parts at the factory, but I'm not holding my breath.
Seems logical based on the prices and descriptions that Z2C refers to the rear M Performance discs, and Z2N refers to the M Performance front and rear calipers and front discs. For some reason the M Performance brakes are broken up that way:
