Supercomp 4-Piston 13-Inch Slotted Big Brake Kit

The Ksport Supercomp Big Brake Kit offers a significant upgrade in stopping power and performance for your BMW X1 E84 models from 2013-2015. This kit is engineered with a focus on reducing brake fade and continuously refreshing the brake pad surface under braking, ensuring consistent performance even under demanding conditions. Key features include a lightweight, one-piece caliper CNC machined from aircraft-quality billet aluminum. This caliper utilizes an opposed piston design to improve pad wear and rigidity over OEM components. It is equipped with aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates. The kit employs a 2-piece disc assembly, which reduces both rotating and unsprung weight for improved vehicle dynamics. The unique slot design on the rotors helps to reduce braking noise and efficiently expel gas and pad debris. Ksport utilizes heat-treated and balanced rotors for optimal performance. For vehicles seeing more track use, slotted rotors are recommended, while cross-drilled rotors are suggested for daily-driven vehicles as they tend to run cooler. This Supercomp Big Brake Kit includes replacement calipers, rotors (330mm x 32mm, slotted, floating), pads, brake lines, and all necessary hardware for a direct bolt-on installation, requiring minimal tools in most applications. The specific fitment is for the BMW X1 E84 2013-2015 with an OE centerbell 185mm width. The calipers come in standard colors like Orange, Red, Yellow, and Black, with custom color options available. All Ksport big brake kits come standard with a 12-month warranty covering manufacturer defects.
