Description

The Ksport Supercomp Big Brake Kit is engineered to deliver the ultimate in stopping power for your vehicle, specifically designed for the 2010-2013 Mazda 3. This kit represents Ksport's most extreme brake upgrade, offering superior performance without the need for any vehicle modifications, as it's a direct bolt-on solution. It builds upon the benefits of the Procomp kit by incorporating larger calipers, rotors, and brake pads, an increased number of pistons, and standard full-floating rotors that enhance caliper self-centering for reduced drag and more even brake application. Construction highlights include lightweight forged one-piece calipers made from aerospace-quality aluminum, ensuring unparalleled strength and freedom from corrosion. These calipers house aluminum pistons, which offer superior heat resistance for consistent operation. The two-piece floating rotor design allows the outer section to shift as needed, further improving self-centering and overall braking performance. Included are SC5 Street Pads, which provide optimal braking for street use and occasional track conditions. These pads are designed to reduce brake dust by over 50% compared to race pads, while also minimizing noise and rotor wear, with an optimal operating temperature range between 194°F - 1022°F. The kit also comes standard with D.O.T. compliant stainless-steel braided brake lines that prevent hose expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel than stock rubber lines. Customers can choose between slotted or cross-drilled rotors, with cross-drilled recommended for daily drivers due to cooler operation, and slotted rotors recommended for track-focused vehicles. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks.
