Show original supplier description
This kit is specifically designed as a direct bolt-on replacement for the 2002-2004 Subaru Impreza STI, requiring no modifications to your vehicle. Constructed with an emphasis on performance and durability, the calipers feature a one-piece design from a solid billet of aircraft-grade aluminum, ensuring light weight and exceptional strength while resisting corrosion. The kit includes aluminum caliper pistons for improved heat resistance and smoother operation, and reinforced carbon steel caliper brackets allow for the direct installation of these larger-than-OEM calipers. The rotors are a 2-piece design with aluminum centers, contributing to lower rotational mass, quicker braking response, and shorter stopping distances. This design also helps reduce the chance of rotor warpage. Heavy-duty caliper seals are included for sustained high-temperature use, and stainless steel brake lines enhance pedal response by preventing expansion under high temperatures and pressures. Key features include 8-piston calipers, 380mm (15-inch) outside diameter drilled and vented rotors, and a minimum wheel diameter requirement of 482.6mm (19 inches). The kit utilizes street-performance brake pads and has a fixed hat construction.
