Show original supplier description
The Ksport Procomp 8-Piston Big Brake Kit offers a significant upgrade in stopping power, specifically engineered to perform under sustained high-heat conditions. The kit features robust 8-piston calipers, constructed from a single billet of aircraft-grade aluminum for exceptional strength, lightweight design, and resistance to corrosion. These calipers utilize aluminum pistons, which enhance heat resistance and ensure reliable operation. The opposed piston design of the calipers greatly improves pad wear and rigidity compared to OEM setups. This kit includes two-piece slotted rotors, providing a balance of lightweight performance, fade resistance on the track, and comfortable operation for daily driving. For added durability and a firmer pedal feel, DOT-compliant stainless-steel braided brake lines are also standard, preventing line expansion under pressure and providing quicker pedal response. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. While Ksport offers a wide array of custom caliper color finishes, this specific kit is for the Mazda 6 from 2002-2008.
