Description

The Ksport Supercomp Big Brake Kit represents the pinnacle of braking upgrades, engineered to deliver exceptional stopping power for your Mazda RX-7 (1986-1991) without necessitating any permanent vehicle modifications. This sophisticated, bolt-on system enhances performance by incorporating larger calipers, rotors, and brake pads, along with an increased piston count. Standard full-floating rotors are included to ensure optimal self-centering within the caliper. The calipers are constructed from a solid billet of aircraft-grade aluminum, forming a lightweight, one-piece forged design that guarantees unparalleled strength and resistance to corrosion. The aluminum pistons within the calipers offer superior heat resistance for uncompromised performance. This kit features a floating two-piece rotor design, allowing the outer section to shift slightly for improved self-centering, reduced brake drag, and more even application. For street and occasional track use, the included NAOC Ceramic SC5 Street Pads offer optimal braking performance while reducing dust by over 50% and minimizing noise and rotor wear. D.O.T compliant stainless-steel braided brake lines are also standard, preventing line expansion under pressure for a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Buyers have extensive customization options for caliper colors and rotor types (Cross Drilled for daily driving, Slotted for track use). Please note that Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. Fitment is confirmed for 1986-1991 Mazda RX-7 Base models.
