Supercomp Rear Big Brake Kit

The Ksport Supercomp Big Brake Kit represents the pinnacle of brake upgrades, engineered to deliver maximum stopping power for your BMW M4 or M3. It builds upon the reputable Procomp kit by incorporating larger calipers, rotors, and brake pads, an increased number of pistons for greater clamping force, and standard full-floating rotors that enhance self-centering for reduced drag and more consistent brake application. The calipers are constructed from a solid billet of aircraft-grade aluminum, ensuring exceptional strength, light weight, and resistance to corrosion. Aluminum pistons are utilized for superior heat management. The two-piece floating rotor design features an outer section that allows for slight movement, improving self-centering and maximizing brake performance. The kit includes Ksport's SC5 Street Pads, formulated with NAOC Ceramic for optimal street and occasional track use, offering reduced dust (by 50% or more), noise, and rotor wear, with an optimal operating temperature range of 194°F - 1022°F. Standard D.O.T. compliant stainless-steel braided brake lines are included, which minimize expansion under pressure, leading to quicker pedal response and a firmer pedal feel. Customers can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily driven vehicles due to better cooling, while slotted rotors are suggested for track-focused applications. Ksport Big Brake kits are built to order and typically require 4-6 weeks for production and delivery. The fitment is specifically for the BMW M3 and M4 models from 2016-2018. Fitment can be confirmed via the search bar on the product page for full compatibility details.
