Description

The Ksport Supercomp Big Brake Kit is engineered to deliver ultimate stopping power for your Acura NSX (1991-1997). This kit integrates advanced brake technology to significantly reduce brake fade and continuously cool the brake pads. The design aims for easy installation with minimal tools required in most applications. Key components include extreme lightweight, one-piece calipers CNC machined from aircraft-quality billet aluminum, featuring differential bore, aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates. The opposed-piston caliper design enhances pad wear and caliper rigidity. Stainless-steel brake lines prevent expansion under pressure, while the 2-piece disc assembly reduces rotational and unsprung weight. Floating disc options are available to mitigate thermal stress and warping. The unique rotor slot design minimizes noise and expels gas and debris effectively. Rotors are heat-treated and balanced for optimal performance, with cross-drilled options for cooler operation and slotted rotors recommended for track use. This specific kit features rear 4-piston calipers and 356mm diameter, 32mm width, slotted, floating rotors. It is available in standard colors like Orange, Red, Yellow, and Black, with over 20,000 custom color options available. The SuperComp rotors include a standard full-floating design for improved self-centering, reduced brake drag, and boosted performance. The kit includes replacement calipers, rotors, pads, brake lines, and all necessary hardware.
