Whiteline Gearbox Positive Shift Kit 2008-2021 WRX / 2008-2021 STI / 2005-2013 LGT / 2009-2013 FXT

The Whiteline 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.
