Description

The Ksport Supercomp Big Brake Kit is engineered as an extreme rear brake upgrade, offering the highest level of stopping power without necessitating any modifications to your vehicle. This sophisticated bolt-on system builds upon the features of the Procomp kit by incorporating larger calipers, rotors, and brake pads, an increased number of pistons, and standard full-floating rotors to enhance caliper self-centering. The calipers are crafted from a solid billet of aircraft-grade aluminum, ensuring a lightweight yet exceptionally strong and corrosion-resistant construction. Aluminum pistons are utilized within the calipers to provide superior heat resistance and maintain consistent operation under demanding conditions. Key features include a lightweight, forged one-piece caliper design for uniform thickness and strength, and CNC-machined carbon steel caliper brackets that facilitate a direct bolt-on installation to your OEM caliper bracket locations. The floating two-piece rotor design allows the outer section to shift as needed, improving self-centering, reducing brake drag, and optimizing performance through more even brake application. Standard with the Supercomp kit are SC5 Street Pads, offering optimal braking performance for street and occasional track use, with reduced dust, noise, and rotor wear. Customers can select between slotted or cross-drilled rotors, with cross-drilled recommended for daily drivers due to cooler running temperatures, and slotted rotors recommended for track-focused vehicles. The kit is built to order, with production and delivery typically taking 4-6 weeks. Ksport Big Brake kits are compatible with a wide range of Mazda RX-8 models from 2003-2012, and buyers are encouraged to use the fitment search tool to confirm compatibility with their specific vehicle year, make, model, and trim.
