Kartboy Transmission Mount Bushings Subaru WRX / STI 2002-2007 / Legacy GT Spec B 2006-2009 / Forester XT 2004-2008
Kartboy transmission mount bushings are made out of a strong urethane to replace the factory bushings that are soft, and become super weak over time. These are going to be installed between the lateral and the horizontal support of the transmission.
With that said the Kartboy transmission mount bushings will eliminate the flex that is caused by replacing the factory mount bushings that are super soft. You’re going to have improvements in the stability of the drivetrain, and you will feel a difference in shifting and you should have a little better improvement in throttle response.
