Description

The Ksport ProComp Big Brake Kit offers enhanced stopping power for your 1987-1992 Toyota Supra. This kit features an 8-piston front caliper system with 356mm (14-inch) two-piece floating disc rotors. The unique slot design on the rotors helps reduce braking noise and efficiently expels gases and pad debris, while the two-piece floating assembly minimizes weight and prevents thermal stress warping. The lightweight aluminum calipers are machined from aircraft-quality billet and feature a differential bore configuration, opposed piston design for improved pad wear and caliper rigidity, aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. Stainless steel braided brake lines are included to prevent expansion under pressure, improving pedal feel and response. This kit comes standard with SC5 Street Pads, designed for optimal street and occasional track use, offering reduced dust and noise compared to race pads. An optional RC1 Race Pad, made of carbon metallic, is available for extreme track conditions. The kit includes CNC-machined carbon steel caliper brackets to ensure a direct bolt-on fit to the OEM caliper bracket location. Ksport backs this big brake kit with a 12-month limited warranty covering manufacturer defects.
