Procomp 8-Piston Front Big Brake Kit

The Ksport Procomp Big Brake Kit is a high-performance front braking system engineered for the Toyota Corolla NZE121 models manufactured between 2003 and 2008, specifically those with a 5x100 bolt pattern. It features a robust 8-piston caliper and a substantial 356mm diameter, 32mm wide drilled rotor, contributing to a superior reduction in brake fade and continuous cooling of the pad surface during braking. The calipers are constructed from a single piece of aircraft-quality billet aluminum, resulting in an exceptionally lightweight yet strong component. They utilize a CNC machined, differential bore design with integrated protection grooves for bridge tubes. Standard features include aluminum pistons, high-temperature seals, and stainless-steel wear plates. The opposed piston caliper design enhances pad wear and caliper rigidity compared to OEM systems, while stainless steel brake lines prevent expansion under pressure for improved pedal response. The kit includes two-piece rotors with aluminum centers to reduce rotational and unsprung weight, minimizing the risk of warping and improving braking response. The specific rotor style, a drilled design, tends to run cooler than slotted rotors and offers increased initial 'bite' while continuously cleaning the pad surface. For street use, the kit is compatible with SC5 Street pads, a low-dust ceramic compound optimal between 194°F and 1022°F. For track enthusiasts, RC1 Race Pads, a carbon metallic compound, can be chosen for maximum stopping power under extreme conditions. The Ksport Procomp Big Brake Kit comes with a standard 12-month warranty covering manufacturer defects.
