Show original supplier description
This rear brake upgrade system utilizes a 4-piston caliper design, with two pistons independently controlling the foot brake and the other two managing the handbrake. Constructed for direct installation without modifications, this kit includes all necessary components: dual-piston calipers, floating brake discs, performance street brake pads, a handbrake, and all required hardware. The calipers feature reinforced carbon steel brackets for a direct bolt-on fit to existing mounting points. Rotors are a 2-piece design with an aluminum center to reduce rotational mass and improve response, while also minimizing the chance of warpage. Key features include drilled rotors with a 330mm (13") outside diameter, vented rotor type, and a fixed hat construction. The orange calipers are designed with opposed-piston geometry to enhance pad grip and reduce uneven wear, while aluminum caliper pistons offer corrosion resistance, better heat management, and lighter weight. Heavy-duty caliper seals are incorporated for sustained high-temperature use, and stainless steel brake lines ensure faster pedal response by preventing expansion under pressure. This kit is compatible with 1993-1998 Subaru Impreza STI models and requires a minimum wheel diameter of 17 inches (432mm).
