Rear

The Supercomp BMW 3 Series Sedan 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 features larger calipers, rotors, and brake pads, increased pistons and standard full-floating rotors for better self-centering in the caliper. All calipers feature 1-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.

Rotor Diameter: 400 (mm) | 15.7 (in)
Position: Rear
Caliper Type: 8 Piston
Rotor Style: Slotted
Note: Ksport Big Brake kits fit 2WD vehicles only unless otherwise stated.
