Whiteline Rear Differential Bushings - 2004-2007 WRX, 2005-2007 STI
These bushings replace the stock bushings in the piece that mounts the stock rear diff mount to the rear diff cross member.
The stock bushings have quite a bit of free play allowing the rear diff to move around under aggressive driving conditions. This movement will often heard through a loud clunk coming from the rear end under hard shifts.
You will notice better throttle response and a more connected feeling to your vehicle.
- This is for the "Differential Mount Support Bar" / "Mustache Bar" bolted to the back of the rear subframe.
- Some WRX / STI models use different support types depending. Please confirm what type you have before ordering.
