Billet Aluminum Big Brake Kit

This sophisticated bolt-on kit builds upon the Procomp system with larger calipers, rotors, and brake pads, more pistons, and standard full-floating rotors that enhance self-centering within the caliper. Constructed from a solid billet of aircraft-grade aluminum, the one-piece calipers offer exceptional lightweight strength and corrosion resistance. The kit includes CNC-machined carbon steel caliper brackets, ensuring a direct bolt-up to OEM caliper bracket locations, even with the larger Ksport calipers. The floating two-piece rotor design is standard, allowing the outer section to shift slightly for better self-centering, reduced brake drag, and improved performance through more even pad application. The kit comes standard with NAOC Ceramic SC5 Street Pads, offering optimal performance for street use and occasional track conditions. These pads reduce brake dust by over 50% and minimize noise and rotor wear, with an optimal operating temperature range of 194°F - 1022°F. D.O.T compliant stainless-steel braided brake lines are also included, providing a quicker pedal response and a firmer pedal feel by eliminating line expansion under pressure. Buyers can choose between slotted or cross-drilled rotors; cross-drilled are recommended for daily drivers due to better cooling, while slotted rotors are suggested for track use. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. This specific kit is designed to fit 2WD Subaru Impreza WRX models from 2008-2014, and also fits various Subaru Impreza WRX and WRX STI models from 2008-2021.
