1-Piece Aircraft-Grade Aluminum Calipers

The calipers are constructed from a single billet of aircraft-grade aluminum, ensuring lightweight strength and corrosion resistance. They also feature aluminum pistons, which offer superior heat resistance compared to standard materials, ensuring uncompromised operation. This kit includes CNC-machined carbon steel caliper brackets that allow the larger Ksport calipers to bolt directly into the OEM caliper bracket locations. The included SC5 Street Pads provide optimal braking performance for street use and occasional track days, reducing brake dust by over 50% and minimizing noise and rotor wear, with an optimal operating temperature range of 194°F - 1022°F. To further enhance performance and user experience, the kit comes standard with D.O.T. compliant stainless-steel braided brake lines, which prevent line expansion under pressure for quicker pedal response and a firmer pedal feel. You can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily driven vehicles due to their cooler running temperatures, while slotted rotors are recommended for track use. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. The calipers come in standard colors like Orange, Red, Black, and Yellow, with options for premium high polish finishes and custom color choices. This kit is specifically designed for the 1998-2005 Lexus GS300, GS400, and GS430 models. Ksport emphasizes that fitment should be confirmed before ordering, and if their sales team confirms fitment and the product does not fit, they will accept returns with no restocking fees, provided the item is in like-new condition.
