Description

The Ksport Supercomp 4-Piston 330mm Rear Big Brake Kit represents the pinnacle of Ksport's brake upgrade offerings, engineered to deliver maximum stopping performance with a direct bolt-on installation. This kit enhances your vehicle's braking system by incorporating larger calipers, rotors, and brake pads, alongside an increased piston count. 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 feature aluminum pistons, which provide superior heat dissipation compared to standard materials, ensuring consistent performance even under demanding conditions. Included with the kit are SC5 Street Pads, which offer a balance of braking performance for both street driving and occasional track use. The optimal operating temperature range for these pads is between 194°F and 1022°F. Additionally, the kit features D.O.T. compliant stainless-steel braided brake lines, which prevent line expansion under pressure, leading to a quicker pedal response and a firmer pedal feel. Customers can choose between slotted or cross-drilled rotors. Cross-drilled rotors are recommended for daily driven vehicles as they run cooler, while slotted rotors are better suited for track use. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. It is crucial to confirm fitment for your specific vehicle, as fitment issues can lead to restocking fees unless an error was made by the sales team or the fitment was confirmed by them and the item is in like-new condition.
