Description

This kit builds upon the renowned Procomp system, incorporating larger calipers, rotors, and brake pads, along with increased piston count and standard full-floating rotors for enhanced self-centering capabilities within the caliper. Constructed from a solid billet of aircraft-grade aluminum, the one-piece calipers are exceptionally lightweight, strong, and resistant to corrosion. The kit also includes CNC-machined carbon steel caliper brackets, ensuring a direct bolt-on fit to your OEM caliper bracket locations despite the larger caliper size. The two-piece floating rotor design allows the outer section to adjust, reducing brake drag and improving performance through more even application. This kit comes standard with Ksport's SC5 Street Pads, made with NAOC Ceramic material. These pads offer optimal braking performance for street use and occasional track days, significantly reducing brake dust (by 50% or more compared to race pads), noise, and rotor wear. They perform optimally in temperatures between 194°F and 1022°F. Also included are D.O.T.-compliant stainless-steel braided brake lines, which prevent expansion under pressure, leading to quicker pedal response and a firmer pedal feel over stock rubber lines. Buyers can choose between slotted or cross-drilled rotors; cross-drilled are recommended for daily drivers due to better cooling, while slotted rotors are suggested for track use. This specific kit is designed for the 2013-2016 Mazda CX-5. Ksport big brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. If fitment issues arise due to a sales team recommendation, the item can be returned with no restocking fees if it remains in like-new condition.
