Kartboy Transmission Mount Bushings - WRX 2002-2007 / STI 2004-2007
The Kartboy Transmission Member Bushings replace the soft rubber bushings with stronger Urethane bushings, reducing the amount of flex in the transmission support. They are placed between the lateral and the horizontal support of the transmission, and eliminate the flex that is caused by having the soft rubber units in place. Improvements will be felt in shifting, and throttle input response.
