Description

The Ksport Supercomp 8 Piston is a front big brake kit designed to provide the highest level of stopping power for your BMW 7 Series (E65/E66) from 2002-2008, including 745i, 745Li, 750i, 750Li, 760i, and 760Li. This kit is our most extreme brake upgrade, engineered as a sophisticated bolt-on solution that requires no vehicle modifications for installation. It builds upon the Procomp kit with larger calipers, rotors, brake pads, and an increased number of pistons. The calipers are constructed from a solid billet of aerospace-quality aluminum, offering lightweight strength and corrosion resistance, and feature aluminum pistons for superior heat management. The Supercomp kit includes standard full-floating rotors, which allow for better self-centering within the caliper, reducing brake drag and enhancing performance through more even application. The rotors are 400mm in diameter and 36mm wide, available in either slotted or cross-drilled configurations. Slotted rotors are recommended for track use, while cross-drilled rotors are suggested for daily drivers as they run cooler. This particular kit features slotted rotors and comes with orange caliper finish, though other colors and premium finishes are available. The kit includes (2) Forged, Monoblock Aluminum Calipers, (2) Lightweight Two-Piece Rotors, a set of SC5 Street Brake Pads, (2) Stainless Steel Brake Lines, and all necessary mounting components and hardware. The SC5 Street Pads offer optimal braking performance for street and occasional track use, reducing dust by 50% compared to race pads and minimizing noise and rotor wear. The stainless-steel braided brake lines provide a firmer pedal feel and quicker response by preventing expansion under pressure. Note that Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. This product contains chemicals known to the State of California to cause cancer and reproductive harm.
