Calipers with Aluminum Pistons and Two-Piece Rotors

The Ksport Procomp Big Brake Kit is engineered as a sophisticated, bolt-on upgrade to significantly enhance your vehicle's braking performance, particularly during sustained high-heat situations. The calipers are constructed from a single billet of aircraft-grade aluminum, offering a combination of lightweight design, exceptional strength, and resistance to corrosion. Inside, aluminum pistons ensure superior heat dissipation and reliable operation. This rear big brake kit features 4-piston lightweight aluminum calipers, designed to improve pad wear and caliper rigidity compared to OEM components. It utilizes two-piece rotors, which provide a balance of light weight, effective grip, and fade-free performance suitable for both track use and comfortable daily driving. The kit also includes D.O.T. compliant stainless-steel braided brake lines, which resist expansion under pressure, leading to quicker pedal response and a firmer pedal feel. Ksport offers customization options for caliper colors and rotor types (slotted or cross-drilled). Included with the kit are SC5 Street Pads, formulated for optimal performance in street driving and occasional track use. These pads offer a 50% reduction in brake dust compared to race pads, while also minimizing noise and rotor wear, with an optimal operating temperature range of 194°F - 1022°F. Ksport Big Brake kits are built to order, and production and delivery typically take 4-6 weeks. The kit is designed for the 2000-2004 Subaru Legacy GT.
