untrue. it's also extra swept area. if we accept: -curb weight -pad surface area/material -pedal pressure -overall tire diameter as constants, then it's going to take a given amount of pad-on-rotor "drag distance" to stop a vehicle from a given speed. a larger rotor means that more of this "drag distance" is covered with each rotation of the roadwheel, thereby stopping the vehicle sooner. larger rotors will also be more heat-resistant, for reasons obvious enough that i don't feel i need to elaborate. jason wall 1995 240sx 1987 gti 16v
