This Kein rear differential mount is a perfect fit for 2008 - 2014 Subaru WRX and STI models. By bolting it onto the inside of the rear sub - frame, it completely eliminates all movement and provides solid support for the rear differential. You'll immediately notice improvements in acceleration, throttle response, and better control when accelerating through corners. It bolts onto existing factory holes, making installation quick and easy. However, be aware that cabin drivetrain noise will increase a bit because it replaces the rubber OEM diff carriers. Key features include eliminating wheel hop and traction loss, K02001/ K02502 steel construction, having passed street and track torture tests, durable powder coating, 65A durometer rubber bushings, and a 2 - year warranty.


Using this Kein rear differential mount is easy. First, find the existing factory holes on the inside of the rear sub - frame of your 2008 - 2014 Subaru WRX or STI. Then, simply bolt the mount onto these holes. You'll start feeling the performance improvements right away. As for the increased drivetrain noise in the cabin, it's just a side - effect of the mount's design, so don't be alarmed. When it comes to maintenance, check the bolts regularly to make sure they're tight. Also, keep an eye on the powder coating. If you notice any chips or scratches, you might want to touch them up to prevent rust.
