The Supercomp BMW Z3 Rear Big Brake Kit is our most extreme brake upgrade, designed to provide the highest level of stopping power without requiring any vehicle modifications to install. This sophisticated bolt-on brake upgrade features the same benefits of our Procomp kit but includes larger calipers, rotors, and brake pads, increased pistons and standard full-floating rotors for better self-centering in the caliper. All calipers feature one-piece construction from a solid billet of aircraft grade aluminum for lightweight, unparalleled strength and freedom from corrosion. Calipers also feature aluminum pistons that provide better heat resistance and uncompromised operation.
The Supercomp Big Brake systems are designed for easy installation with minimal tools required in most applications. Standard brake upgrade kit includes replacement calipers, rotors, pads, brake lines, and related hardware. With carefully designed features, unparalleled strength and upgrades available for kit customization, the Supercomp BMW Z3 Rear Big Brake Kit provides the ultimate in stopping power for your vehicle. This system is appropriate for 15.7” wheels and above.
