Pro-Comp Billet Aluminum Big Brake Kit

This kit builds upon the foundation of the Procomp system, incorporating significantly larger calipers, rotors, and brake pads, alongside an increased piston count for superior hydraulic force. The calipers are meticulously crafted from a single billet of aircraft-grade aluminum, ensuring a lightweight yet incredibly strong and corrosion-free component. Standard on the Supercomp system are floating two-piece rotors, which feature an outer section that allows for slight movement. This design improves self-centering within the caliper, reducing drag and ensuring more even pad application for enhanced braking efficiency. Ksport also offers extensive customization options for caliper colors, including standard painted finishes and premium high-polish options. The kit includes NAOC Ceramic SC5 Street Pads, which provide excellent performance for daily driving and occasional track use while significantly reducing brake dust (by 50% or more), noise, and rotor wear. These pads operate optimally between 194°F and 1022°F. Further enhancing the braking system are D.O.T. compliant stainless-steel braided brake lines, which minimize expansion under pressure for a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Buyers can choose between slotted or cross-drilled rotors; slotted rotors are recommended for track use, while cross-drilled rotors are suggested for daily driven vehicles due to their cooler operating temperatures. Please note that Ksport Big Brake kits are built to order and typically require 4-6 weeks for production and delivery. This kit is specifically designed for the 1989-1995 BMW 5 Series models (E34), including the 525i, 530i, 535i, and 540i.
