Big brake systems were not designed to stop your car sooner, but rather, stop it more efficiently and consistently. The larger calipers, vented discs, and exotic-compound pads increase heat capacity and heat dissipation. These upgraded braking systems not only perform well under extreme temperatures, but in most cases perform better when hot as opposed to average street driving temperatures. This is definitely something to consider when deciding on rotor and pad compounds. Because these brakes dissipate heat more effectively, they reduce brake fade. Brake fade occurs under high temperatures, can be caused by boiled brake fluid, and results in a soft pedal and elongated stopping distances. Big brake systems don't decrease your car's stopping distance over stock. Instead, they are designed to perform consistently under extreme conditions so that your car will stop just as well the first time.
