Slimline 330mm Slotted Front Big Brake Kit

The Ksport Slimline 3-Piston Big Brake Kit is engineered to provide a significant upgrade in braking performance for 1998-2005 Lexus GS300, GS400, and GS430 models. This front-axle kit features a 330mm rotor size and a 3-piston caliper design, which is notably slimmer than typical multi-piston calipers, allowing for compatibility with factory wheels or those with minimal caliper clearance. This addresses a common challenge where aggressive wheel fitments prevent the installation of larger brake systems. Included in the kit are two-piece rotors, chosen here in a slotted style for enhanced track performance, and SC5 Street Pads. These pads offer a balance of braking power suitable for daily driving and occasional track use, while also reducing dust and noise compared to race-oriented pads. The system is completed with D.O.T.-compliant stainless steel braided brake lines, which prevent expansion under pressure, leading to a firmer pedal feel and quicker response compared to stock rubber lines. Ksport manufactures these Big Brake Kits to order, so please anticipate a production and delivery lead time of 4-6 weeks. This kit is confirmed to fit various trims of the 1998-2005 Lexus GS300, GS400, and GS430. Fitment should be double-checked using the vehicle search tool to ensure compatibility with your specific vehicle configuration.
