F1 cars run something like 10.9" diameter rotors.

With fresh tires, I'm hitting over 120mph on our front straight and mash on them well into the markers. I will be going for 300whp for next years season and will continue to run the 12.9" rotor. I believe rthorne might have the larger rotor StopTech kit, but he also has like 700whp and drives it like a pro driver should.

FYI: 355 mm is 13.9", not 15".
