6-Piston Caliper Kit

The Ksport Procomp Big Brake Kit offers a significant upgrade for your BMW 3 Series, engineered to enhance braking performance under demanding high-heat conditions. This kit is designed as a sophisticated, bolt-on solution that requires minimal tools for installation in most applications. Constructed from a solid billet of aircraft-grade aluminum, the 6-piston calipers are both lightweight and exceptionally strong, ensuring durability and resistance to corrosion. They feature aluminum pistons that improve heat resistance and maintain uncompromised operation. This Procomp kit comes standard with SC5 Street Pads, a NAOC Ceramic compound that delivers optimal braking for street use and occasional track days. These pads significantly reduce brake dust by over 50% compared to race pads, while also minimizing noise and rotor wear. The optimal operating temperature range for these pads is between 194°F and 1022°F. Furthermore, the kit includes D.O.T compliant stainless-steel braided brake lines. These lines prevent expansion under pressure, leading to quicker pedal response and a firmer pedal feel compared to stock rubber lines. Customers can choose between Slotted or Cross Drilled rotors. Cross Drilled rotors are recommended for daily driven vehicles due to their cooler running temperatures, while Slotted rotors are advised for vehicles that will be used more frequently on the track. This Ksport Procomp Big Brake Kit is specifically designed for the BMW 3 Series E30 models from 1982-1992, including the 316, 318, 320, 323, and 325 variants. Please note that Ksport Big Brake kits are built to order, and production and delivery typically take 4-6 weeks.
