Description

The Ksport Supercomp 8-Piston Big Brake Kit represents Ksport's most extreme brake upgrade, engineered to deliver unparalleled stopping power without requiring any modifications to your vehicle. This sophisticated, bolt-on system builds upon the benefits of their Procomp kit by incorporating larger calipers, rotors, and brake pads, an increased number of pistons, and standard full-floating rotors for enhanced self-centering capabilities within the caliper. The calipers are meticulously crafted from a single billet of aircraft-grade aluminum, ensuring a lightweight yet exceptionally strong and corrosion-resistant structure. Aluminum pistons are employed to provide superior heat resistance and maintain uncompromised operational integrity. The floating two-piece rotor design allows the outer section to shift as needed, promoting better self-centering, reduced brake drag, and more even pad application for improved performance. Ksport offers extensive customization options for caliper colors, including standard finishes like orange, red, black, and yellow, as well as premium high-polish options in silver, gold, and titanium, with over 20,000 custom color finishes available. The kit includes SC5 Street Pads, which provide optimal braking performance for street and occasional track use, reducing brake dust by over 50% and minimizing noise and rotor wear, with an optimal operating temperature range of 194°F - 1022°F. Additionally, D.O.T. compliant stainless-steel braided brake lines are standard, offering a quicker pedal response and firmer pedal feel by preventing line expansion under pressure. Customers can choose between slotted or cross-drilled rotors. Cross-drilled rotors are recommended for daily-driven vehicles as they run cooler, while slotted rotors are suggested for vehicles that will see more track time. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. This kit is specifically designed to fit the Mazda RX-7 models from 1993 to 1996, with specific fitment listed for 1993 and 1995 Base models, and a general note that the item fits a ton of vehicles, encouraging users to search the full list.
