Product Description
The factory shifter in an STi has a shift throw of 40mm per gate; the GFB unit is adjustable from the factory setting, right down to a tiny 22mm per gate! To put this into perspective, the best any aftermarket shifter (that replaces only the gearstick) can hope to achieve is 30mm per gate, without modifications to the linkages or surrounding bodywork. The photos opposite show the stock STi shifter vs the GFB shifter from 3rd to 4th gear.

Installation is done completely from within the car, and is made much easier with the inclusion of a special tool for removal and installation of the reverse lock-out cable pin. Typically the installation can be completed within 20 minutes.
