The Cusco 22mm rear sway bar is specified for GDB(C) Impreza STI models to increase rear anti-roll stiffness and enhance cornering stability. It improves rear-end control under load and works as a direct replacement for the factory component. Install this bar during suspension upgrades or when refreshing the rear stabilizer to achieve firmer handling on GDB(C) STI chassis.
