8-Piston Calipers

Constructed with meticulous attention to detail, the kit features 8-piston calipers crafted from a solid billet of aircraft-grade aluminum. This one-piece design ensures exceptional strength, reduced weight, and resistance to corrosion. The calipers are equipped with aluminum pistons, offering superior heat management and long-term durability. The rotors are a 2-piece design, incorporating a fixed hat construction made from cast iron with a slotted, vented surface. This configuration not only contributes to lower rotational mass for quicker response but also helps mitigate rotor warp and efficiently expel heat and debris. Key benefits include an opposed-piston caliper design that enhances pad grip and minimizes uneven wear. The minimum wheel diameter required is 17 inches (432mm), with an outside rotor diameter of 13 inches (330mm). This ProComp Big Brake Kit is specifically designed for the 2003-2007 Mitsubishi Evolution 8 and 9 models. The kit includes everything needed for the upgrade, and it comes with the manufacturer's standard warranty.
