Cusco Rear Differential Support Brace - FRS/BRZ/86
Cusco Rear Differential Support Brace. The Cusco rear diff support brace eliminates ALL movement of the rear differential. By bolting this unit onto the backside of the rear sub-frame, the brace will support the rear differential. This takes the job away from the soft stock bushings which deflect under hard acceleration. Improvement will instantly be felt in acceleration, throttle response, and improved control of the car when using the throttle to help the rotation.
The Brace bolts on to existing factory holes, making this a quick and easy install. However, be warned that in-cabin drivetrain noise will increase slightly due to the nature of eliminating rubber OEM diff carriers.
