8-Piston 380mm Slotted Rotor Big Brake Kit

This sophisticated, bolt-on system builds upon the advantages of KSport's Procomp kit, incorporating larger calipers, rotors, and brake pads, an increased number of pistons, and standard full-floating rotors for superior self-centering capabilities within the caliper. Constructed with a focus on strength and lightness, the calipers are forged from a single billet of aerospace-grade aluminum, ensuring exceptional durability and corrosion resistance. They feature aluminum pistons that enhance heat resistance and maintain performance under demanding conditions. The floating two-piece rotor design allows the outer section to shift slightly, improving self-centering, reducing brake drag, and ultimately boosting performance through more even application. Included with the kit are KSport's SC5 Street Pads, formulated with NAOC Ceramic material for optimal performance on the street and during occasional track use. These pads significantly reduce brake dust by over 50% compared to race pads, while also minimizing noise and rotor wear, operating effectively between 194°F and 1022°F. The braking system is further enhanced by D.O.T. compliant stainless-steel braided brake lines, which eliminate line expansion under pressure, leading to a quicker pedal response and a firmer pedal feel than stock rubber lines. Buyers can choose between slotted or cross-drilled rotors, with slotted recommended for track use and cross-drilled for daily driving due to cooler operation. This Ksport Big Brake Kit is custom-built to order, with production and delivery typically taking 4-6 weeks. It is specifically designed to fit various models of the BMW 6 Series from 2004 to 2011, including the E63/E64 chassis and the M6 variant. Fitment for specific trims like the 645Ci, 650Ci, and 650i within these model years has been confirmed. If you are unsure about compatibility, Fitment Industries' sales team can confirm fitment to reduce the risk of ordering the wrong product; if their team confirms fitment and the product does not fit, they will accept returns with no restocking fees, provided the item is in like-new condition.
