M2 Competition 2NH brakes feature the F8x carbon ceramic brake’s calipers (F&R) with 400mm/380mm steel rotors. And the F10 M5 standard brake’s front calipers are the same as F8x CCB front calipers.
Standard M2/M2C brakes (blue) (source: see here): - blue front caliper - 4.890 kg or 10.78 lbs
- blue rear Caliper - 3.600 kg or 7.94 lbs
- 380x30mm front rotor - 11.300 kg or 24.91 lbs
- 370x24mm rear rotor - 9.300 kg or 20.50 lbs
= 58.180 kg or 128.26 lbs
2NH M Sport Brakes (silver) - M Performance Parts Brakes (red): - silver/red front caliper - 7.540 kg or 16.62 lbs
- silver/red rear Caliper - 4.310 kg or 9.50 lbs
- 400x36mm front rotor - 13.870 kg or 30.58
- 380x30mm rear rotor - 11.300 kg or 24.91
= 74.040 kg or 163.23 lbs
Extra weight of the optimized silver/red brakes compared to the standard blue M2/M2C brakes = 15.86 kg or 34.97 lbs |
Came to realize that the M2C big brake rear rotor weight are over quoted here. They should read 9.5kg/21.0lb, for a total weight difference of
12.5kg / 27.5lb.
