Cusco Strut Bar OS Rear JZS161 GS400 GS430

This is a Cusco OS (Over-Steering) Rear Strut Bar designed for your 1998-2000 Lexus GS400. When you're pushing your car through corners, the chassis can flex, especially around the rear suspension mounting points. This strut bar connects those points directly, making the chassis more rigid. That improved rigidity means your suspension can do its job more effectively, leading to better handling and a more connected feel to the road.

Cusco builds these bars with strong steel tubing, and the mounting brackets are well-made to ensure a solid connection. The OS design uses a larger diameter bar, which offers a bit more stiffness compared to smaller bars. Installation is typically a straightforward bolt-on process, connecting to existing points on the strut towers. You'll notice a difference in how the car responds when you turn the wheel, especially during spirited driving or on winding roads.
