Description

This bolt-on system builds upon the Procomp kit with larger calipers, rotors, and brake pads, enhanced piston count, and standard full-floating rotors for superior self-centering. Each caliper is precision CNC machined from a solid billet of aircraft-grade aluminum, ensuring lightweight construction, unparalleled strength, and resistance to corrosion. Aluminum pistons are utilized for improved heat resistance and consistent performance. Ksport's Supercomp kits feature carbon steel caliper brackets, CNC machined to facilitate a direct bolt-on installation to OEM caliper bracket locations, accommodating the larger Ksport calipers. The rotors are a floating two-piece design, allowing the outer section to self-center, which reduces brake drag and improves braking performance through more even pad application. These kits include NAOC Ceramic SC5 Street Pads, offering optimal braking for street and occasional track use, with significantly reduced dust and noise compared to race pads, and an operating temperature range of 194°F - 1022°F. The system is completed with D.O.T. compliant stainless-steel braided brake lines, which prevent expansion under pressure for quicker pedal response and a firmer pedal feel. Ksport offers customization for rotors, with options for cross-drilled (recommended for daily drivers for cooler operation) or slotted (recommended for track use) designs. Calipers are available in standard painted colors (Orange, Red, Black, Yellow) and can be upgraded to premium high-polish finishes or custom colors. This kit is built to order, with production and delivery typically taking 4-6 weeks. The fitment is specifically for the 1986-1991 Mazda RX-7.
