The Ksport DualComp Big Brake Kit provides a significant upgrade for the braking system of 1998-2005 Lexus GS300, GS400, and GS430 vehicles. This rear kit includes 4-piston calipers and 14-inch fixed rotors, available in either cross-drilled or slotted options to suit your driving needs. Cross-drilled rotors offer improved cooling for daily driving, while slotted rotors are recommended for track applications. The kit is a complete bolt-on system, providing everything necessary for installation, including calipers, floating brake discs, brake pads, and handbrake components. Ksport Big Brake kits are specifically designed to fit 2WD vehicles only, unless otherwise stated. This particular kit is confirmed to fit 1998-2005 Lexus GS300, GS400, and GS430 models.
