Show original supplier description

The Ksport Slimline 3 Piston 350mm Front Big Brake Kit offers a significant upgrade in stopping power and aesthetics for your Lexus GS300, GS400, or GS430 from 1998-2005. Engineered with aggressive fitting wheels in mind, the Slimline Caliper design maintains a thickness similar to OEM single-side piston calipers, allowing compatibility with factory wheels or those with limited caliper clearance. For optimal street and occasional track use, the kit comes with SC5 Street Pads, which reduce dust by over 50% and minimize noise and rotor wear. The D.O.T. compliant stainless-steel braided brake lines enhance pedal response and firmness by eliminating line expansion under pressure. Customize your brake setup with a choice between cross-drilled rotors, recommended for cooler operation and daily driving, or slotted rotors, ideal for track applications. Calipers are standard in red, orange, black, or yellow, with options for premium high-polish finishes (silver, gold, titanium) and over 20,000 custom color choices. The kit also features CNC-machined carbon steel caliper brackets to ensure a direct bolt-on fit to your vehicle's OEM caliper bracket location. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks.
