DualComp Rear Big Brake Kit

The Ksport DualComp Big Brake Kit is engineered as a comprehensive rear braking solution for Lexus GS300, GS400, and GS430 models spanning the years 1998 through 2005. This advanced system employs a unique Dual Caliper configuration, integrating a single 4-piston caliper that splits its function: two pistons operate the primary foot brake, while the other two independently manage the handbrake system. This innovative design ensures enhanced braking performance and control. Constructed with performance and durability in mind, the kit includes CNC-machined carbon steel caliper brackets for a direct bolt-on fit to OEM locations. It features lightweight, two-piece floating brake discs, available in either cross-drilled or slotted options, with cross-drilled recommended for daily driving and slotted for track use. The kit comes standard with SC5 NAOC Ceramic brake pads, designed to offer optimal street and occasional track performance with reduced dust and noise. Completing the package are D.O.T. compliant stainless-steel braided brake lines, which minimize line expansion for a firmer pedal feel and quicker response, and a distinctive polished Titanium handbrake lever and cylinder for precise control and aesthetic appeal. Ksport emphasizes that these big brake kits are built to order, requiring an estimated production and delivery time of 4-6 weeks. While the kit is designed as a complete bolt-on solution, it's crucial to confirm fitment for your specific vehicle configuration. Fitment is confirmed for 1998-2005 Lexus GS300, GS400, and GS430 models. The manufacturer also notes that Ksport Big Brake kits are designed for 2WD vehicles.
