4-Piston Big Brake Kit

The kit includes robust 4-piston calipers, finished in an eye-catching orange, paired with 330mm (13") slotted and vented 2-piece rotors made from durable cast iron. The calipers are constructed from a single billet of aircraft-grade aluminum, ensuring both lightweight design and exceptional strength while resisting corrosion. The use of aluminum caliper pistons further enhances heat resistance and reduces overall weight. The 2-piece rotor design features an aluminum center to decrease rotational mass and improve braking response, while also minimizing the risk of warping due to thermal expansion. Designed for performance and racing applications, this big brake kit is compatible with 17" wheels and larger. The opposed-piston caliper design optimizes pad grip, leading to more even wear and consistent stopping power. Heavy-duty caliper seals are incorporated for sustained high-temperature use, and the included stainless steel brake lines prevent expansion under pressure, resulting in a firmer and more responsive pedal feel. This Ksport ProComp Big Brake Kit is specifically designed for the 2003-2007 Mitsubishi Evolution models.
