Description

Designed as a sophisticated, bolt-on modification, it installs without requiring any vehicle modifications. This kit builds upon the benefits of Ksport's Procomp kit, featuring larger calipers, rotors, and brake pads, along with an increased number of pistons per caliper. Standard full-floating rotors are included for improved self-centering within the caliper, which helps to reduce brake drag and enhance overall performance through more even application. Ksport emphasizes quality construction with its Supercomp Big Brake Kit. The calipers are crafted from a solid billet of aircraft-grade aluminum in a one-piece forged construction, ensuring lightweight design, unparalleled strength, and resistance to corrosion. Aluminum pistons are utilized within the calipers to provide superior heat resistance and maintain uncompromised operation under demanding conditions. The braking system includes floating two-piece rotors, a standard feature on all Supercomp models. These rotors allow the outer section to shift slightly as needed, improving self-centering capabilities within the caliper for reduced brake drag and more consistent braking force. Customization options are available for the rotors, with choices between slotted or cross-drilled designs. Cross-drilled rotors are recommended for daily driven vehicles due to better cooling, while slotted rotors are suggested for vehicles with more track use. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. This kit is specifically designed to fit 2006-2012 Lexus GS models, including the GS300, GS350, and GS430. It is important to note that this kit excludes AWD models.
