Product reviews for Cusco Rear Differential Power Brace-FRS/86/BRZ (965-488-A)

When upgrading the intake and exhaust. I got a bit of noise of noise and vibration increase. With the increased power, you need better more stiffer bushings and braces to cover the shortfalls. This piece does that and more. Once installed I got a huge decrease in noise and vibrations on lower RPMs. When pushing over 5k rpm, same low noise and vibrations. It provides sharper shifting and I feel more grip to the wheels now. I would consider this a great product in conjunction with Whiteline bushings.
