Cusco’s 22mm rear sway bar for the Subaru Impreza WRX STi (VAB) is 130% stiffer than the OEM unit. A thicker rear sway bar reduces roll, allowing the car to corner flatter. The thicker rear sway bar will induce more oversteer, therefore it is recommended to upgrade the front OEM sway bar to a similar sized one to balance the handling.
All Cusco’s sway bars come with two sway bar bushes to suit the car.
