Description

Each caliper is precision CNC machined from a solid billet of aircraft-grade aluminum, ensuring a lightweight yet exceptionally strong and corrosion-free component. The calipers utilize aluminum pistons, which offer enhanced heat resistance for consistent performance. Featuring a two-piece rotor design, this kit minimizes weight and provides fade-free performance, effective grip on the track, and comfortable operation for daily driving. The kit includes Ksport's SC5 Ceramic pads, designed for optimal braking in street and occasional track use, significantly reducing dust and noise while maintaining performance between 194°F and 1022°F. Additionally, DOT-compliant stainless-steel braided brake lines are standard, improving pedal response and feel by eliminating expansion under pressure. Customers can choose between slotted or cross-drilled rotors: cross-drilled for cooler operation recommended for daily drivers, and slotted for enhanced track performance. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. This kit fits the Mazda RX-7 from 1986 to 1991, specifically for 2WD vehicles.
