The NEUSPEED short shift kit for the 2005-up Golf V, Jetta V, and Passat B6 easily installs onto the transmission's selector shaft.  The Neuspeed short shift kit reduces the throw length between gears by approximately 40% - this is the absolute maximum reduction possible without overextending the cable mechanism. 

The NEUSPEED short shift kit incorporates a calibrated counterweight which is required for more positive shift action.  Lookout for kits without the counterweight, as they will produce very notchy gear selection. 

This is a completely bolt-on application - no cable adjustment required.
