Show original supplier description
The Ksport Procomp Audi S2 Big Brake Kit offers a sophisticated, direct-fit solution to significantly improve your vehicle's stopping power, especially under sustained high-heat conditions. Each caliper is precision-machined from a solid billet of aerospace-quality aluminum, ensuring unparalleled strength, light weight, and resistance to corrosion. The opposed-piston design promotes consistent brake pad wear and rigidity, while aluminum pistons enhance heat dissipation and maintain smooth operation. High-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates are standard features. The kit is compatible with 16-inch wheels and larger and is specifically designed for 2WD vehicles. The 6061-T6 aircraft-grade aluminum center sections reduce rotational mass for quicker stopping and improved brake response. This design also minimizes rotor warping by allowing the outer friction ring to expand and contract independently. Customers can choose between cross-drilled rotors, recommended for daily driving due to better cooling, or slotted rotors, ideal for track use as they help dissipate heat, dust, and gases more effectively. All rotors are heat-treated and balanced for optimal performance. Included in the standard kit are forged, monoblock aluminum calipers, lightweight two-piece rotors (slotted or drilled), a set of SC5 Street Brake Pads, stainless steel brake lines, all necessary mounting components and hardware, and an owner's manual. The kit also offers customization options for center bell finishes and caliper colors. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks.
