Supercomp Big Brake Kit

The Ksport Supercomp Big Brake Kit represents Ksport's most extreme brake upgrade, engineered to deliver unparalleled stopping power for your Mazda 3 (2004-2009) without requiring any vehicle modifications. This kit builds upon the Procomp system with larger calipers, rotors, and pads, enhanced piston count, and standard full-floating rotors that improve self-centering within the caliper for reduced drag and more even application. Construction highlights include one-piece forged calipers from aerospace-grade aluminum for exceptional strength and corrosion resistance, and aluminum pistons for superior heat management. Standard SC5 NAOC Ceramic pads offer optimal performance for street and occasional track use, significantly reducing brake dust, noise, and rotor wear, with an optimal operating temperature range of 194°F - 1022°F. For enhanced customization and performance, the kit includes D.O.T. compliant stainless-steel braided brake lines that eliminate line expansion under pressure, leading to a quicker pedal response and firmer pedal feel. Buyers can choose between slotted or cross-drilled rotors; slotted rotors are recommended for track use due to better heat dissipation, while cross-drilled rotors are suggested for daily drivers as they run cooler. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. Fitment is confirmed for various Mazda 3 models from 2004 to 2009, and Fitment Industries encourages users to verify compatibility for their specific vehicle using the search bar if it's not listed.
