Description

The Ksport Supercomp Big Brake Kit is engineered as the most extreme brake upgrade available, offering unparalleled stopping power for your Mazda 3 (2014-2016) without requiring vehicle modifications for installation. This sophisticated, bolt-on system enhances the performance of the Procomp kit with larger calipers, rotors, and brake pads, an increased number of pistons, and standard full-floating rotors for superior self-centering capabilities within the caliper. Each caliper is meticulously crafted from a single billet of aircraft-grade aluminum, ensuring lightweight construction, exceptional strength, and resistance to corrosion. The calipers also incorporate aluminum pistons, which provide improved heat resistance and maintain uncompromised operation under demanding conditions. The kit features a one-piece forged caliper design, offering a perfect balance of even thickness and robust strength. The floating two-piece rotor design allows the outer section to shift as needed, enhancing self-centering, reducing brake drag, and optimizing performance through more consistent application. Buyers can choose between slotted or cross-drilled rotors, with cross-drilled recommended for cooler operation on daily driven vehicles and slotted rotors preferred for track use. The kit includes SC5 Street Pads, made with NAOC Ceramic material for optimal street and occasional track performance, significantly reducing brake dust, noise, and rotor wear, with optimal operating temperatures between 194°F - 1022°F. Additionally, D.O.T compliant stainless-steel braided brake lines are standard, reducing line expansion under pressure for a quicker pedal response and a firmer pedal feel. Ksport Big Brake kits are built to order and typically require 4-6 weeks for production and delivery. This kit is designed for 2WD vehicles only.
