8R Big Brake Kit

The Ksport Procomp Big Brake Kit offers a significant upgrade in stopping performance for your vehicle. The kit's calipers are constructed from aircraft-quality billet, featuring a differential bore and an extreme lightweight design. Internally, they are equipped with aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates for durability and heat resistance. This braking system utilizes a 2-piece floating disc assembly, which contributes to reduced rotating and unsprung weight. The unique slot design on the rotors is optimized to minimize braking noise and efficiently expel gas and pad debris, outperforming conventional designs. For optimal performance and longevity, each rotor is heat-treated and balanced before shipment. The kit also includes stainless steel brake lines, which prevent expansion under pressure, ensuring a firm and consistent pedal feel. The specific application for this Ksport Procomp Big Brake Kit (BKAU220-971SO) is the 2005-2008 Audi S4 B7 Chassis. The kit features a SuperComp 8 Piston caliper in red, with a rotor diameter of 421mm (16.5 inches) and a slotted style.
