1-Piece Aircraft-Grade Aluminum Calipers

The calipers are constructed from a single billet of aircraft-grade aluminum, ensuring lightweight, unparalleled strength, and resistance to corrosion. They feature aluminum pistons that offer superior heat resistance and maintain uncompromised operation even under demanding use. The opposed piston caliper design inherently improves pad wear and caliper rigidity compared to OEM components. This rear big brake kit utilizes two-piece rotors, providing a lightweight solution that delivers fade-free performance and effective grip on the track, while also ensuring comfortable, user-friendly operation for daily driving. For customization, Ksport offers options for both slotted and cross-drilled rotors; cross-drilled rotors are recommended for daily drivers as they run cooler, while slotted rotors are suggested for vehicles primarily used for track driving. The kit includes SC5 Street Pads, formulated with NAOC Ceramic for optimal braking in street and occasional track conditions, reducing brake dust by over 50% and minimizing noise and rotor wear with optimal operating temperatures between 194°F - 1022°F. Furthermore, D.O.T compliant stainless-steel braided brake lines are standard, preventing hose expansion under pressure for quicker pedal response and a firmer pedal feel over stock rubber lines. Ksport Big Brake kits are built to order, and customers should anticipate a production and delivery time of 4-6 weeks. The available fitment includes specific Lexus GS350 and GS430 models from 2006 to 2012. If fitment issues arise, Ksport or its authorized sellers will work with customers to find a resolution, especially if fitment was confirmed by their sales team and the item does not fit, in which case returns may be accepted without restocking fees if the item remains in like-new condition.
