Cusco Rear Upper Arm Kit 2008-2022 WRX / STI
Increasing the vehicle track width with low offset wheels can lead to a number of issues like off-center loading, and alignment swing arc. To do this properly without losing suspension capability and effectively enhancing performance with wider track, Cusco has created a number of components. For the rear, we have an adjustable upper and lower arm set which enable just that. These not only allow proper loading of rear suspension, brakes, and hub components, it will allow a wider choice of wheel and tire widths to be properly set. Suggested use with other Cusco suspension parts to allow maximum adjustment range and bushings/joint loading characters.
