Description

This sophisticated, bolt-on system builds upon the Procomp kit's capabilities, incorporating larger calipers, rotors, and brake pads, along with increased pistons and standard full-floating rotors that enhance self-centering within the caliper. The calipers themselves are precision-crafted from a single billet of aircraft-grade aluminum, ensuring a lightweight yet incredibly strong and corrosion-free component. Aluminum pistons are utilized for superior heat resistance and reliable operation. Buyers can choose between slotted or cross-drilled rotors, with cross-drilled recommended for daily drivers seeking cooler operation and slotted for track-focused applications. Standard SC5 Street Pads offer optimal performance for street and occasional track use, reducing dust by over 50% while minimizing noise and rotor wear, with an optimal operating temperature range of 194°F - 1022°F. D.O.T. compliant stainless-steel braided brake lines are included to prevent line expansion under pressure, resulting in quicker pedal response and a firmer pedal feel. Ksport Big Brake kits are built to order, and customers should anticipate a production and delivery time of 4-6 weeks. While the kit is designed for broad fitment on certain Mazda 3 models (2010-2013), it is crucial to verify compatibility with your specific vehicle. Fitment Industries advises customers to confirm fitment before ordering to avoid potential issues. If the sales team confirms fitment and the product does not fit, the item can be returned with no restocking fees, provided it is in like-new condition.
