4-Piston 330mm Big Brake Kit

The Ksport ProComp Big Brake Kit offers a sophisticated bolt-on solution to significantly upgrade your vehicle's braking performance, especially under the demanding conditions of sustained high heat. Constructed with performance and durability in mind, the kit features 4-piston calipers with a 1-piece billet aircraft-grade aluminum construction for lightweight strength and corrosion resistance. The aluminum caliper pistons offer superior heat resistance and uncompromised operation. The rotors are a 2-piece vented design with drilled cast iron braking surfaces and aluminum centers, reducing rotational mass, improving response, and minimizing the risk of warping. Reinforced carbon steel caliper brackets allow for direct bolt-on installation to existing mounting points. The overall rotor diameter is 330mm (13"), and a minimum wheel diameter of 432mm (17") is required. This kit is specifically designed for the 2003-2007 Mitsubishi Evolution 8 and 9 models. It comes with stainless steel brake lines that resist expansion under high temperatures and pressures, leading to faster pedal response.
