The Brembo front GTS big brake kit for 2006–2011 Lexus GS300 replaces front components with six-piston cast calipers and two-piece 355x32mm drilled rotors in black. Provided as a front-specific upgrade, the kit expands rotor area and uses multi-piston clamping to improve brake bite and reduce fade, delivering more consistent stopping performance for Lexus GS300 models within the listed year range.
