agreed. pecivil's point, however, is still valid for track scenarios. a higher HP car will see higher average speeds around a track (given equal chassis). accordingly, the kinetic energy the brakes will have to shed increases. this will increase heat. as a brake system essentially changes kinetic energy to thermal energy, the job of a brake rotor is to get rid of that heat, hence the larger system. on the road, this makes almost no difference. on the track, it makes a LOT of difference.

Hi,

No disagreement here...
