Big Brake Kit

The Ksport Supercomp 4-Piston Rear Big Brake Kit represents Ksport's most extreme brake upgrade, engineered to deliver unparalleled stopping power without requiring any vehicle modifications for installation. This sophisticated, bolt-on system 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 for enhanced caliper self-centering. The calipers are precision-machined from a solid billet of aircraft-grade aluminum, ensuring a lightweight yet incredibly strong and corrosion-resistant construction. These calipers also feature aluminum pistons, which offer superior heat resistance and maintain optimal performance under demanding conditions. The kit includes SC5 Street Pads, formulated with NAOC Ceramic for optimal street and occasional track use, offering a significant reduction in brake dust, noise, and rotor wear, with an optimal operating temperature range between 194°F - 1022°F. DOT compliant stainless-steel braided brake lines are also standard, preventing line expansion under pressure for a quicker pedal response and a firmer pedal feel. The Supercomp system utilizes a floating two-piece rotor design, allowing the outer section to shift slightly for better self-centering within the caliper. This design minimizes brake drag and enhances performance through more even application. Buyers can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily-driven vehicles due to their cooler running temperatures, while slotted rotors are advised for vehicles frequently used on the track. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. Customization options for caliper colors, including standard finishes like Orange, Red, Black, and Yellow, as well as premium high polish options in Silver, Gold, and Titanium, are available, with over 20,000 custom color finishes possible. This specific kit is designed for the 2002-2008 Mazda 6. It is important to confirm fitment for your specific vehicle year, make, model, and trim. Fitment Industries emphasizes that if their sales team recommends an incompatible setup, they will work with the customer to resolve the issue, potentially waiving restocking fees if the item is in like-new condition.
