Description

The Ksport Supercomp Big Brake Kit represents the pinnacle of their brake upgrade offerings, engineered to deliver maximum stopping power for your Mazda 6 (2009-2013) with a straightforward bolt-on installation. Building upon the foundation of their Procomp kit, the Supercomp model boasts larger calipers, rotors, and brake pads, in addition to an increased number of pistons. This enhanced configuration, combined with standard full-floating rotors, ensures superior self-centering within the caliper for optimized performance. Constructed from a solid billet of aircraft-grade aluminum, the one-piece calipers are exceptionally lightweight, incredibly strong, and resistant to corrosion. These calipers also incorporate aluminum pistons, which offer superior heat resistance and maintain uncompromised operation even under demanding conditions. Furthermore, the floating two-piece rotor design allows the outer section of the rotor to shift, promoting better self-centering within the caliper, reducing brake drag, and improving braking consistency. Included with the kit are SC5 Street Pads, formulated with NAOC Ceramic for optimal performance on the street and occasional track use. These pads offer a significant reduction in brake dust (over 50% compared to race pads), noise, and rotor wear, with an optimal operating temperature range between 194°F - 1022°F. The kit also features D.O.T. compliant stainless-steel braided brake lines, which prevent expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to standard rubber lines. Buyers can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily drivers due to better cooling, while slotted rotors are suggested for track-focused vehicles. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. This kit is specifically designed for the 2009-2013 Mazda 6 GS trim. While the product listing indicates compatibility with a wide range of vehicles, it is essential to confirm fitment for your specific vehicle using the search bar provided.
