1-Piece Billet Aluminum Caliper

This kit is specifically designed for the 2002-2007 Subaru Impreza WRX, offering a direct replacement for existing components without requiring modifications. All calipers in this kit feature a 1-piece construction from a solid billet of aircraft-grade aluminum, ensuring light weight, unparalleled strength, and freedom from corrosion. The opposed-piston caliper design significantly improves pad grip and minimizes uneven wear. Additionally, aluminum caliper pistons provide enhanced heat resistance and prevent corrosion, contributing to uncompromised operation. Reinforced carbon steel caliper brackets are included, allowing these larger-than-OEM size calipers to bolt directly onto existing mounting points. The kit includes 380mm (15") 2-piece vented rotors with drilled surfaces and aluminum centers, which reduce rotational mass, quicken braking response, and shorten 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. All caliper seals are heavy-duty for sustained high-temperature racetrack use, and stainless steel brake lines prevent expansion under high temperatures and pressures, leading to faster pedal response. This kit requires a minimum wheel diameter of 19 inches. The driving style recommended for this kit is Performance / Racing, and it comes with street-performance brake pads.
