Show original supplier description
The Ksport Supercomp Big Brake Kit represents the pinnacle of braking upgrades, engineered to deliver maximum stopping power for your Audi S4 without requiring any permanent vehicle modifications. This kit builds upon the features of Ksport's Procomp line, offering substantially larger calipers, rotors, and brake pads, along with an increased number of pistons for enhanced hydraulic leverage. The standard full-floating rotor design promotes better self-centering within the caliper, which reduces brake drag and improves the consistency and power of your braking. Constructed from a solid billet of aircraft-grade aluminum, the one-piece calipers are exceptionally lightweight yet incredibly strong and resistant to corrosion. These calipers also incorporate aluminum pistons, which offer superior heat management compared to other materials, ensuring uncompromised performance even under demanding conditions. The floating two-piece rotor design allows the outer braking surface to articulate slightly, aiding in self-centering and ensuring more even pad application for reduced drag and improved performance. Included with the kit are SC5 Street Pads, which provide optimal braking performance for both street driving and occasional track use. These pads offer a significant reduction in brake dust and wear compared to race pads, while also minimizing noise and rotor wear. The optimal operating temperature range for these pads is between 194°F and 1022°F. Complementing the system are D.O.T. compliant stainless-steel braided brake lines, which eliminate line expansion under pressure, leading to a quicker pedal response and a firmer pedal feel than stock rubber lines. For rotor customization, you can choose between slotted or cross-drilled rotors; slotted rotors are recommended for track use due to better heat dissipation, while cross-drilled rotors offer cooler operation for daily driven vehicles. Ksport Big Brake kits are built to order and typically require 4-6 weeks for production and delivery. This kit is designed for 2WD vehicles only.
