The Cusco 21mm rear sway bar is specified for the GC8 Subaru Impreza application. As a direct-fit Cusco component, it replaces the factory rear stabilizer bar with a thicker 21mm diameter unit to alter roll stiffness and balance. Intended for drivers seeking a chassis upgrade with model-specific fitment, it integrates into existing suspension mounting points without requiring broad vehicle modifications.
