Description

The Ksport Supercomp Big Brake Kit represents the pinnacle of brake upgrade technology for the Mazda CX-5, engineered to deliver unparalleled stopping power. This kit is designed as a direct bolt-on solution, eliminating the need for any vehicle modifications. It builds upon the Procomp kit's capabilities with larger calipers, rotors, and brake pads, enhanced piston count, and standard full-floating rotors that promote better self-centering within the caliper, reducing brake drag and improving performance. The one-piece forged caliper construction from aerospace-grade aluminum ensures exceptional strength, lightness, and resistance to corrosion, while aluminum pistons offer superior heat management. Key components include CNC-machined carbon steel caliper brackets that facilitate a direct bolt-up to OEM caliper locations, despite the larger caliper size. The floating two-piece rotor design allows for slight adjustments, further contributing to efficient braking and optimal performance. Included are SC5 Street Pads, which offer a balance of braking performance for street and occasional track use, significantly reducing brake dust and noise compared to race pads. Customers can choose between slotted or cross-drilled rotors. Cross-drilled rotors are recommended for daily drivers due to better cooling, while slotted rotors are suggested for track use. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. The kit is specified for the 2013-2016 Mazda CX-5, with specific fitment confirmed for Grand Touring trims in those model years. The seller notes that if fitment issues arise due to their recommendations, they will work to resolve the situation and may waive fees if the item is in like-new condition.
