means more stopping power. It does not require as much clamping force to slow the wheel at the same rate as a stock sized rotor simply because of leverage. If I were to guage it, I would say I am pressing on the brake pedal about 2/3 of the force it would require with stock rotors to stop in the same distance.
From a thermodynamic standpoint, the factor that is affected by moving outward from the axis is disc speed. The disc is moving at a faster rate the further out you go. What this means is that it will transfer heat to the rotor quicker, but not more heat. This is the factor that makes a brake stop better; the rate of transfer of kinetic energy into thermal energy. The quicker you transfer the heat, the quicker you are stopping. However, the disc has to be capable of absorbing enough heat to slow you down withouot getting so hot that it begins vaporizing the pad and steel of the rotor; this is what causes brake fade. Using a more massive rotor gives you the thermal capacity such that you dont reach that point, or you just reach it at a later point.
