Overview

This kit features larger-diameter disc rotors and calipers constructed from a solid billet of aircraft-grade aluminum for light weight and strength. The opposed-piston caliper design improves pad grip and reduces uneven wear, while aluminum pistons offer better heat resistance and corrosion freedom.
Show original supplier description
This kit features robust 4-piston calipers, each crafted from a single billet of aircraft-grade aluminum for exceptional strength, light weight, and corrosion resistance. The calipers house aluminum pistons that enhance heat resistance and ensure smoother operation. The kit includes 330mm (13-inch) diameter, 2-piece disc rotors that are both slotted and vented. The 2-piece design, featuring an aluminum center, reduces rotational mass, leading to quicker braking response and shorter stopping distances. This construction also helps mitigate rotor warpage by allowing for more free expansion and contraction of the outer iron section. The street-oriented pad type ensures good performance for a variety of driving conditions. The opposed-piston caliper design significantly improves pad grip and minimizes uneven wear. All caliper seals are heavy-duty, built to withstand sustained high-temperature racetrack use, and the included stainless steel brake lines resist expansion under pressure for a firmer pedal feel. This kit is specifically designed for the 2002-2004 Subaru Impreza STI models. It requires a minimum wheel diameter of 17 inches (432mm).
