1-Piece Billet Aluminum Caliper with Aluminum Pistons

The Ksport Procomp 4-Piston 330mm Rear Big Brake Kit is a sophisticated bolt-on upgrade engineered to significantly enhance braking power, especially under sustained high-heat conditions. Each caliper is meticulously crafted from a single billet of aircraft-grade aluminum, ensuring lightweight construction, unparalleled strength, and resistance to corrosion. The calipers are further enhanced with aluminum pistons, which offer superior heat resistance and maintain optimal performance. This kit includes two-piece rotors, which contribute to reduced weight and provide fade-free performance and effective grip, suitable for both racetrack use and comfortable daily driving. The kit comes standard with D.O.T. compliant stainless-steel braided brake lines, which eliminate line expansion under pressure for quicker pedal response and a firmer pedal feel compared to stock rubber lines. Included are SC5 Street Pads, formulated from NAOC Ceramic material to provide optimal braking performance for street and occasional track use. These pads offer a significant reduction in brake dust (50% or more) and noise compared to race pads, while minimizing rotor wear. They operate effectively within a temperature range of 194°F to 1022°F. The rotors are available in either Cross Drilled or Slotted options; Cross Drilled rotors are recommended for daily drivers due to better cooling, while Slotted rotors are advised for vehicles seeing more track time. Ksport Big Brake kits are built to order, and production and delivery typically take 4-6 weeks. If fitment is confirmed by a sales team representative and the product does not fit, the item can be returned in like-new condition without restocking fees.
