#9241, "RE: Q about AEM big brake kit.." In response to In response to 0
I believe the big brake kit comes with larger rotors and a caliper relocation spacer. Larger rotors will give you a longer moment arm from your pads to the center of rotation which gives you greater stopping power. Larger pads would arguably help as well, but contact area has never really been proven to affect friction. Friction force is determined by the normal force (piston) and the coefficient of friction (metal rotors to whatever type of pads you use).
anyways, enough theory. I think you can see the big brakes will help you stop faster even with the same pads.
