DualComp Rear Big Brake Kit

This kit utilizes a unique DualComp system, featuring a single 4-piston caliper designed with two independent circuits: two pistons for the primary foot brake and two for the handbrake. Key components include opposed-piston calipers that improve pad grip and reduce uneven wear, aluminum pistons for corrosion resistance and heat management, and reinforced carbon steel caliper brackets that allow for larger-than-OEM calipers. The 2-piece floating brake discs have aluminum centers to reduce rotational mass and quicken response, while also minimizing the chance of rotor warpage due to less restricted expansion and contraction. Heavy-duty caliper seals are included for sustained high-temperature use, and stainless steel brake lines ensure a faster pedal response by preventing expansion under pressure. The kit is designed to fit 2008-2014 Subaru Impreza WRX models and requires a minimum wheel diameter of 17 inches (432mm). The calipers are finished in an orange color, and the rotors are drilled and vented with an outside diameter of 330mm (13 inches).
