Supercomp 4-Piston Big Brake Kit with Slotted Rotors

The Ksport BKLX060-437SO Supercomp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to deliver the highest level of stopping power available. Featuring full-floating two-piece rotor construction and a 4-piston caliper configuration, this kit is built for drivers who demand maximum braking performance on both the street and the track. Floating Rotor Technology is central to this kit's performance. The two-piece floating disc assembly significantly reduces both rotating and unsprung weight. This floating design also prevents thermal stresses from warping the disc or cupping the braking surface under extreme heat. The slotted rotor design rapidly expels gas and pad debris while continuously cleaning and refreshing the pad surface, making it the preferred choice for track and performance-oriented driving. Key features include CNC machined calipers from a single billet of aircraft-grade aluminum, ensuring uniform strength and corrosion resistance without casting or welding. These calipers weigh approximately 5 lbs each, contributing to substantial unsprung weight reduction over stock. Mounting brackets and caliper slides are included, and anti-rattle springs are also provided. Pad shims are not included.
