The Supercomp Acura NSX 14″ Rear Big Brake System 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.
