Featuring 12.88-inch rotors with excellent stopping power and enhanced performance, users can choose from either a SRP drilled and slotted rotor or a GT competition series face slotted rotor. Calipers are available with either a glossy black or a red powder coated finish, and use BP compound SmartPads for high performance response on the street or at the track.

All necessary hardware for installation, along with DOT-compliant stainless steel braided flex lines, and a detailed instruction guide are included with the kit to ensure an effortless, bolt-on process.
