6-Piston Calipers with Aluminum Pistons

The calipers are constructed from a solid billet of aircraft-grade aluminum, offering a superior strength-to-weight ratio and excellent resistance to corrosion. They feature a 1-piece design and opposed-piston configuration to maximize pad grip and minimize uneven wear. The aluminum caliper pistons are chosen for their better heat resistance and lighter weight compared to traditional materials. Reinforced carbon steel caliper brackets ensure these larger-than-OEM calipers mount directly to existing points. The kit includes 2-piece vented rotors with a cast iron braking surface and a fixed aluminum center hat. This design reduces rotational mass, leading to quicker braking response and shorter stopping distances. The 2-piece construction also allows for greater thermal expansion of the outer iron section, reducing the risk of rotor warping. Heavy-duty caliper seals are incorporated for sustained high-temperature racetrack use, and stainless steel brake lines prevent expansion under pressure for faster pedal response. This ProComp Big Brake Kit is specifically designed for the 2017-2019 Honda Civic Type R. It requires a minimum wheel diameter of 19 inches (482.6mm) and uses street-performance pads. The calipers are finished in an eye-catching orange color, and the rotors are slotted for improved heat dissipation and pad cleaning.
