Supercomp 8-Piston Big Brake Kit

The Ksport Supercomp Big Brake Kit represents the pinnacle of braking enhancement for your BMW 8 Series, engineered to deliver maximum stopping power without requiring any modifications to your vehicle. Building upon the features of their Procomp kit, the Supercomp version boasts larger calipers, rotors, and brake pads, along with an increased number of pistons and standard full-floating rotors for superior self-centering within the caliper. The calipers are forged from a single billet of aircraft-grade aluminum, ensuring lightweight construction, unparalleled strength, and resistance to corrosion. Inside, aluminum pistons offer enhanced heat resistance and reliable operation. These high-performance calipers are paired with CNC-machined carbon steel caliper brackets that allow for a direct bolt-on installation to the OEM caliper bracket location. Standard on all Supercomp systems are floating two-piece rotors. This feature reduces brake drag and improves overall performance through more consistent application. The kit comes standard with SC5 Street Pads, composed of NAOC Ceramic material, which provide optimal braking performance for street driving and occasional track use. These pads are formulated to reduce brake dust by 50% or more compared to race pads, while also minimizing noise and rotor wear. They are effective within an operating temperature range of 194°F to 1022°F. Additionally, the kit includes D.O.T. compliant stainless-steel braided brake lines. These lines prevent expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Buyers can choose between slotted or cross-drilled rotors. Cross-drilled rotors are recommended for daily driven vehicles as they dissipate heat more effectively, while slotted rotors are suggested for vehicles that see more track time. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. This kit is specifically designed for the 1990-1994 BMW 8 Series, including models like the 850i.
