The CP5144 calipers are far stiffer than stock and use a commonly available pad shape. They improve pedal feel, increase fade resistance, and can be run with the OEM rear discs or other aftermarket discs.
The basic pad shape for the CP5100 caliper was created by many years ago, and is used by a wide range of racing calipers today. They're available in just about every popular racing compound on the market. That means you’ll never end up in a pinch without pads.
