Beatrush rear diff support bar eliminates ALL movement of the rear differential. By bolting this unit onto the back side 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 in improved control of the car when using the throttle to help 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.
Classic GC8 also available.
