Cusco Sway 18mm Rear JZS161 GS400

Cusco is well-known for making performance suspension parts, and this 18mm rear sway bar is a solid option for your JZS161 GS400. If you're looking to dial in your car's handling and reduce that feeling of body roll when you take corners, a stiffer rear sway bar like this one can make a notable difference. It works by connecting the left and right sides of your suspension, resisting the body's tendency to lean.

This sway bar is constructed from solid steel, giving it the strength needed to effectively control body movement. The 18mm diameter is a common upgrade size that offers a good balance between improved handling and maintaining a comfortable ride for daily driving. It's designed to fit your JZS161 GS400, meaning it should install without major modifications, though you'll want to refer to the manufacturer's instructions for the specific procedure.
