Description

The Ksport Supercomp Big Brake Kit represents the pinnacle of braking upgrades, engineered to deliver exceptional stopping power for your Audi S3 (2000-2003). This sophisticated, bolt-on system integrates larger calipers, rotors, and pads, along with an increased piston count, to significantly enhance your vehicle's braking performance. The kit utilizes standard full-floating rotors, which offer better self-centering within the caliper, reducing brake drag and ensuring more consistent application. Constructed with precision, Ksport's calipers are forged from a single billet of aircraft-grade aluminum, ensuring a lightweight yet incredibly strong and corrosion-resistant component. These calipers feature aluminum pistons for superior heat resistance and reliable operation. The kit includes NAOC Ceramic SC5 Street Pads, which provide optimal braking performance for street and occasional track use, while reducing brake dust by over 50% and minimizing noise and rotor wear. D.O.T. compliant stainless-steel braided brake lines are also standard, offering a firmer pedal feel and quicker response by eliminating line expansion under pressure. You can choose between slotted or cross-drilled rotors; slotted is recommended for track use, while cross-drilled is ideal for daily drivers due to better cooling. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks.
