Supercomp Rear Big Brake Kit

The Ksport Supercomp Big Brake Kit represents the pinnacle of Ksport's brake upgrade offerings, specifically engineered for the Lexus GS350 and GS430 models from 2006 to 2012. The Supercomp kit elevates performance beyond the Procomp line by incorporating larger calipers, rotors, and brake pads, along with increased piston count. A key feature is the standard full-floating rotor design, which allows for better self-centering within the caliper, leading to reduced brake drag and more consistent braking performance. The calipers themselves are a testament to Ksport's engineering, featuring a one-piece forged construction from aerospace-quality aluminum. This method ensures exceptional strength, light weight, and resistance to corrosion. Aluminum pistons are utilized within the calipers to better manage heat and maintain optimal operation under demanding conditions. Further enhancing the kit's performance and customization are several distinct components. The caliper brackets are CNC machined from carbon steel to allow the larger Ksport calipers to bolt directly onto the OEM caliper bracket locations. The kit includes SC5 Street Pads, formulated for optimal performance on the street and occasional track use, offering a 50% reduction in brake dust compared to race pads, along with reduced noise and rotor wear. D.O.T compliant stainless-steel braided brake lines are also standard, providing a firmer pedal feel and quicker response by preventing line expansion under pressure. For rotor customization, customers can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily drivers due to better cooling, while slotted rotors are advised for track-focused vehicles. This big brake kit is built to order, and customers should expect a production and delivery lead time of 4-6 weeks. Fitment is confirmed for various Lexus GS350 and GS430 models within the 2006-2012 range, with specific trims and engines listed.
