6-Piston Big Brake Kit with Slotted Rotors

The Ksport Procomp 4 Piston Rear Big Brake Kit is engineered as a sophisticated, bolt-on upgrade to significantly enhance braking power, especially under demanding high-heat conditions. The calipers are constructed from a single billet of aircraft-grade aluminum, ensuring lightweight strength and corrosion resistance, and feature aluminum pistons for superior heat management. This design improves pad wear and caliper rigidity compared to OEM components. It also features D.O.T. compliant stainless steel braided brake lines that reduce line expansion under pressure, leading to quicker pedal response and a firmer pedal feel. The included SC5 Street Pads offer a balance of performance for street and occasional track use, minimizing brake dust and noise. The kit comes with custom caliper options, allowing for various color choices, and CNC machined carbon steel caliper brackets that facilitate direct bolt-on installation to OEM caliper bracket locations. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. This specific kit is compatible with the 2006-2010 BMW M5 Base model.
