4002 Specific Features

Following on from our popular WRX short-shift kit, we have now released a new version to suit Subaru’s 6-speed gearbox found in all late-model STi’s, from MY02 and on.
As with our WRX kit, the GFB STi short shift kit includes a unique clamp arrangement that allows the shift throw to be reduced much more than by changing the gearstick alone. As you can see from the picture, the GFB clamp eliminates the need to lift the gearbox linkage higher to reduce shift throw. Instead, you simply select one of the three holes.
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.

FAQ

I've heard bad stories of gearbox damage from using a short shifter, is this true?

TLDR: Absolutely not!

We’ve heard this concern many times, often from ‘internet experts’, and surprisingly even from so-called ‘performance mechanics’. Read on, and you can smile to yourself knowing that when someone claims to have damaged their gearbox because of a short shifter, it’s more likely they are in fact a sloppy driver.

Here’s the hard truth – a gearstick is simply a lever, connecting the driver’s hand to the gearbox. Any wear or damage is proportional only to the way in which it is used (or abused!), no if’s, but’s or maybe’s about it. If you shift hard and fast (or time the clutch poorly), the synchros will wear out faster regardless of what type of shifter you have.

The GFB Short Shifter reduces the travel of the gearstick – if you reduce the throw by 20%, there is a 20% increase in the effort required to shift gears – this is the very basic principle of levers. Whilst this increase in shift effort may give the feeling that you are stressing the ‘box more by having to push the stick harder, you are in fact exerting the same shifting force to the gearbox. Additionally, the reduced throw may falsely lead the unsympathetic driver to believe faster shifts can be performed – you can only shift as fast as the synchros will allow.

How much lower is a GFB shifter than the factory one?

The GFB Short Shifter is the same height as the factory shifter, it is the actual distance that the gear stick moves between gears that is reduced.
