Supercomp 356mm Slotted Rear Big Brake Kit

The Ksport Supercomp Big Brake Kit is an extreme brake upgrade engineered to deliver superior stopping power for your BMW X1 E84 (2013-2015). Designed as a sophisticated bolt-on system, it installs without requiring any vehicle modifications, offering a significant enhancement over stock braking capabilities. This kit features a 356mm slotted two-piece rotor and a lightweight, forged one-piece aluminum caliper with 4 pistons. The calipers are constructed from a solid billet of aerospace-quality aluminum for exceptional strength and corrosion resistance, incorporating aluminum pistons for improved heat management. Carbon steel caliper brackets ensure a direct fit to the OEM caliper location, while the floating rotor design allows for slight adjustments, promoting better self-centering, reduced brake drag, and more even application for boosted performance. Stainless steel braided brake lines are included to prevent line expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel. The Supercomp kit comes standard with SC5 Street Brake Pads, which offer optimal performance for street and occasional track use, while reducing brake dust by over 50% and minimizing rotor noise and wear. Ksport also offers a wide range of custom caliper color options, including standard painted colors (Orange, Red, Black, Yellow) and premium high-polish or anodized finishes. Note that Ksport Big Brake kits are built to order, and production and delivery typically take 4-6 weeks.
