8-Piston Big Brake Kit with 13.38" Rotors

This kit features significantly larger diameter disc rotors and aggressive 8-piston calipers, optimized for performance and racing driving styles. Constructed for durability and reduced weight, each caliper is milled from a solid billet of aircraft-grade aluminum, ensuring unparalleled strength and resistance to corrosion. The opposed-piston caliper design maximizes pad contact for superior grip and minimizes uneven pad wear. Furthermore, the aluminum caliper pistons contribute to better heat management and corrosion-free operation. The kit also utilizes reinforced carbon steel caliper brackets, allowing these oversized calipers to mount directly to the vehicle's existing points without modification. The inclusion of stainless steel brake lines ensures a firm pedal feel under high temperatures and pressures by preventing line expansion. The SuperComp rotors are designed with a standard full-floating configuration, promoting self-centering within the caliper to reduce drag and enhance overall braking performance. These rotors are a 2-piece design, incorporating an aluminum center to decrease rotational mass, leading to quicker response times and shorter stopping distances. This construction also mitigates rotor warpage by allowing for more unrestricted expansion and contraction of the outer iron braking surface. Heavy-duty caliper seals are incorporated for sustained high-temperature use, making this kit suitable for demanding track conditions. All components are engineered as a direct bolt-on replacement, requiring no modifications to the vehicle. This kit is specifically designed for the 2015-2018 Subaru WRX and requires a minimum wheel diameter of 19 inches (482.6mm). The rotors measure 380mm (15 inches) in outside diameter. The kit includes two SuperComp Big Brake Kits. It comes with the Manufacturers Standard Warranty.
