4003 Specific Features

• More affordable alternative to STi’s own aftermarket shifter.

• Easily upgraded to the 4002 kit with the addition of the linkage clamp. 

4003 Specific FAQ

So why choose the Basic over the 4002 kit?
When using the full 4002 kit, some people find that the shorter settings are actually too extreme for their taste (particularly on MY06-08 models, as the factory shift is shorter than earlier versions), and only end up using a small amount of the shifter’s range. In such cases, the Basic kit gives the same result at a lower price. If however you decide that you want to go shorter, you can always purchase the linkage clamp separately and upgrade to the full 4002 kit at a later date – it really is win-win! As with the 4002 full kit, installation of the Basic kit is all done from within the car in about 30 minutes, and is made all the easier with the inclusion of GFB’s brilliant and unique pin-press tool – when you use it you’ll know why we included it and wonder why others don’t!

So how much shorter is the throw?

The GFB Basic kit is adjustable from the factory setting down to around 32-35mm per gate (depending on year model). Add the linkage clamp and the possible throw range drops to a miniscule 20-22mm (see photos opposite – these show the factory shifter vs the GFB full kit on a 3rd to 4th gearshift)!

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.
