Description

Building upon the benefits of their Procomp kit, the Supercomp features significantly larger calipers, rotors, and pads, along with an increased number of pistons and standard full-floating rotors for optimized self-centering and reduced drag. Each caliper is precision-machined from a solid billet of aerospace-grade aluminum, ensuring exceptional lightweight strength and long-term corrosion resistance, while aluminum pistons further enhance heat dissipation and operational reliability. The floating two-piece rotor design allows for slight adjustments, promoting better self-centering within the caliper, minimizing brake drag, and ensuring more consistent pad application for enhanced performance. Buyers can choose between slotted or cross-drilled rotors, with cross-drilled recommended for daily drivers due to better cooling, and slotted rotors for track-focused vehicles. The kit comes standard with SC5 NAOC Ceramic pads, offering optimal performance for street and occasional track use, characterized by reduced dust (by 50% or more), noise, and rotor wear, with an optimal operating temperature range of 194°F - 1022°F. Additionally, D.O.T. compliant stainless-steel braided brake lines are included to prevent line expansion under pressure, leading to quicker pedal response and a firmer pedal feel. Ksport Big Brake kits are built to order and require an estimated 4-6 weeks for production and delivery. The Supercomp kit is specifically designed for the 2009-2013 Mazda 6, excluding the Mazdaspeed model. Fitment should be confirmed using the vehicle search tool, as the item fits a wide range of vehicles beyond those listed.
