This is a combo for the Kartboy STi short throw shifter and STi front and rear shifter bushings. You only need to order this to get all three parts.

The Kartboy replacement lever for the Subaru WRX STi 6 Speed is the first non-Subaru version available. With a height reduction of 1" and a redesigned mechanical advantage, a throw reduction of 40% is achieved. CNC machined and Tig welded in the USA. Matched with a set of Kartboy front and rear shifter bushings, a major improvement in the shifting is immediately felt, while retaining the factory reverse lock-out

The Kartboy Shifter Bushings replace the stock shifter mount bushings in the 2004+ Subaru WRX STI. While this product will not change the geometry of the shifting mechanism, it eliminates excessive play in the system for a more solid gear change. This simple modification will make your shifter linkage feel 10x more solid. This product requires jacking of the car and jackstands are mandatory. Can be installed in 30 min. Material is Grey for the STI. Made in USA
