Supercomp 8 Piston 400mm Rear Big Brake Kit

The Ksport Supercomp 8 Piston 400mm Rear Big Brake Kit represents the pinnacle of Ksport's braking upgrades, engineered for extreme stopping power. This sophisticated bolt-on system integrates advanced brake technology to significantly reduce brake fade and maintain optimal pad surface temperature during braking. The kit features larger calipers, rotors, and brake pads compared to Ksport's Procomp series, along with an increased piston count and standard full-floating rotors for enhanced self-centering within the caliper. Constructed from a solid billet of aircraft-grade aluminum, the one-piece caliper design offers exceptional lightweight strength and corrosion resistance. The calipers are equipped with aluminum pistons for superior heat management and high-temperature seals. The braking system also includes CNC-machined carbon steel caliper brackets to ensure a direct bolt-on installation to OEM caliper bracket locations. The two-piece floating rotor design allows the outer section to shift slightly, improving self-centering, reducing drag, and boosting performance through more even pad application. Rotors are available in slotted (recommended for track use) or cross-drilled (recommended for daily driving) options, and are heat-treated and balanced for optimal performance. Included with the kit are SC5 Street Pads, designed for optimal braking performance under street and occasional track conditions, offering a 50% reduction in brake dust compared to race pads, along with reduced noise and rotor wear. Ksport also includes D.O.T. compliant stainless-steel braided brake lines, which prevent expansion under pressure, leading to quicker pedal response and a firmer pedal feel. The company offers a wide array of custom caliper color options, including standard painted finishes and premium high-polish or anodized options, with over 20,000 custom color finishes available. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. Fitment is available for various Subaru Legacy models from 2010-2013, with a broader compatibility list accessible through the vehicle search bar. In cases where fitment is confirmed by the sales team and the item does not fit, returns are accepted in like-new condition without restocking fees.
