Overview

The Ksport SuperComp Big Brake Kit is an extreme brake upgrade designed for the 1993-2001 Subaru Impreza STI. It provides the highest level of stopping power with larger-diameter disc rotors. All calipers are constructed from a solid billet of aircraft-grade aluminum for light weight and strength, featuring aluminum pistons for better heat resistance.
Show original supplier description
Each caliper is constructed from a single billet of aircraft-grade aluminum, ensuring both light weight and exceptional strength while resisting corrosion. The calipers feature aluminum pistons, which offer superior heat resistance and smoother operation compared to traditional materials. For optimal brake grip and reduced uneven wear, an opposed-piston caliper design is utilized. The 2-piece rotors, measuring 380mm (15 inches) in diameter, are constructed from cast iron with a 2-piece design incorporating an aluminum center. This configuration reduces rotational mass, leading to quicker braking response and shorter stopping distances. The 2-piece design also minimizes the chance of rotor warpage by allowing for less restricted expansion and contraction of the outer iron section. For sustained high-temperature performance, all caliper seals are heavy-duty, and stainless steel brake lines are included to prevent expansion under pressure, ensuring faster pedal response. This kit requires a minimum wheel diameter of 19 inches (482.6mm) and utilizes street-performance brake pads. The rotors are vented and drilled for enhanced cooling and performance. All components are included for a straightforward installation.
