Description

The Ksport Supercomp Big Brake System is an extreme brake upgrade designed for the Audi A3, offering unparalleled stopping power with a direct bolt-on installation. This sophisticated system includes larger calipers, rotors, and brake pads, along with an increased piston count and standard full-floating rotors for optimized self-centering. Each caliper is forged from a solid billet of aircraft-grade aluminum, ensuring lightweight strength and freedom from corrosion. Aluminum pistons are incorporated for superior heat resistance and uncompromised operation, even under demanding conditions. The two-piece rotor design contributes to lightweight construction and fade-free performance, suitable for both track and daily driving. The rotors can be specified as either cross-drilled for cooler operation or slotted for enhanced performance during track use. For serious track drivers, the "full floating" rotor design allows the outer section to shift slightly, reducing brake drag and improving performance through more even application. The system includes 8-pot lightweight aluminum calipers, two-piece rotors (14-inch diameter), SC5 Street Brake Pads, stainless steel brake lines, and all necessary mounting hardware. The calipers are compatible with 18-inch wheels and above. Ksport offers a 12-month limited warranty against manufacturer defects.
