Overview

The Ksport Supercomp Big Brake Kit is a rear brake upgrade designed for the Acura NSX (1991-1997 NA1). This kit offers an extreme level of stopping power and is a direct bolt-on installation without requiring vehicle modifications. It features larger calipers, rotors, and brake pads than the Procomp kit, with increased pistons and standard full-floating rotors for better self-centering.

All calipers are constructed from a one-piece billet of aircraft-grade aluminum for lightweight strength and corrosion resistance. The kit includes aluminum pistons for better heat resistance and caliper brackets made of CNC-machined carbon steel to ensure proper fitment.
Show original supplier description
This advanced, bolt-on system builds upon the Procomp kit by incorporating larger calipers, rotors, and brake pads, along with increased piston count and standard full-floating rotors for enhanced self-centering and reduced drag. The calipers are meticulously crafted from a solid billet of aircraft-grade aluminum, ensuring a lightweight yet incredibly strong and corrosion-resistant construction. These calipers also feature aluminum pistons, which offer superior heat resistance and reliable operation under demanding conditions. The kit includes SC5 Street Pads, providing optimal braking performance for street and occasional track use, with a significant reduction in dust and noise compared to race pads. D.O.T. compliant stainless-steel braided brake lines are also standard, improving pedal response and feel by eliminating expansion under pressure. Ksport offers customization options for rotors, allowing you to choose between slotted or cross-drilled designs. Cross-drilled rotors are recommended for daily drivers due to their superior cooling, while slotted rotors are better suited for track-focused vehicles. Calipers are available in standard painted colors like Orange, Red, Black, and Yellow, with premium high-polish finishes and custom color options also available. This rear big brake kit is specifically designed for the 1991-1997 Acura NSX. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. If an issue arises due to an error on our part, including situations where our sales team has recommended an incompatible setup, we will work with you to resolve it.
