Description

The Ksport Supercomp Big Brake Kit provides the ultimate in stopping power for your Mazda 6 (2002-2008). Integrating advanced brake technology, this kit significantly reduces brake fade and continually cools the brake pad surface during braking. Each caliper is crafted from a solid billet of aircraft-quality aluminum, featuring a one-piece construction for extreme lightness and unparalleled strength. The opposed-piston caliper design improves pad grip and minimizes uneven wear, while aluminum pistons offer corrosion resistance and superior heat management. The kit includes a 2-piece rotor assembly with an aluminum center to reduce rotational mass, leading to quicker braking response and shorter stopping distances. This design also minimizes rotor warpage by allowing for more restricted expansion and contraction of the outer iron section. The rotor features a unique slot design to reduce noise and expel gases and debris more efficiently. For street use, SC5 Street pads with a long-lasting, low-dust ceramic compound are recommended, while RC1 Race Pads are available for track applications. All Ksport big brake kits come with a standard 12-month warranty covering manufacturer defects. This Supercomp kit is specifically designed for the Mazda 6 models from 2002 to 2008, excluding the Mazdaspeed model. It includes replacement calipers, rotors, pads, brake lines, and all necessary hardware. Available rotor sizes are 356mm diameter and 32mm width, with a floating disc design. Calipers are available in 4-piston configurations and standard colors like Orange, Red, Yellow, and Black, with over 20,000 custom color options.
