Description

Its Slimline Caliper design mimics the thickness of OEM single-piston calipers, allowing for significant brake upgrades even with limited wheel clearance. This kit ensures that your vehicle can benefit from enhanced braking power while maintaining compatibility with most factory or tight-fit aftermarket wheels. This front brake system features a 3-piston caliper configuration, providing improved stopping power over stock systems. The kit includes lightweight, two-piece 350mm drilled rotors, known for their ability to run cooler than slotted rotors, making them ideal for daily driven vehicles. The pads operate effectively in a temperature range of 194°F to 1022°F. Construction includes CNC-machined carbon steel caliper brackets for a direct bolt-on installation to the OEM caliper bracket location. The kit also comes with D.O.T compliant stainless steel braided brake lines, which eliminate line expansion under pressure for quicker pedal response and a firmer pedal feel. Standard kit components include forged monoblock aluminum calipers, lightweight two-piece rotors (slotted or drilled options available), a set of SC5 Street Brake Pads, stainless steel brake lines, all necessary mounting hardware, and an owner's manual. This Big Brake Kit is specifically designed for the Lexus GS models from 2006 to 2012, including the GS300, GS350, and GS430, but it excludes AWD models. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks.
