This is true, but there are other constraints that must be considered. If you understand this concept you may realize that a very short top section, and very long bottom section would result in the shortest throws (taken to the extreme, your hand would simply be holding onto the linkage to shift). Either of these things can be done independently, but they are most often done at the same time to provide the best results. This changes the length of the throw by reducing the leverage (and actually will marginally increase the overall height of the shifter if nothing else is changed). The second change is to increase the distance between the pivot ball and the linkage connection (I will refer to this as the "bottom"). This obviously will also decrease the overall height of the shifter. I will be referring to this as the "top" (distance between linkage connection and the top of the shifter). This reduces the amount you have to move your hand in order to shift into gear, simply by placing your hand closer to the linkage. The first is the overall height of the shifter. There are two aspects that can be changed in regard to shifter throw. Skip this part if you already understand what a short shifter does. In most aftermarket shifters both of these things are true. Others think of it as having shorter shifts. Some people think of a short shifter as being physically shorter. It is not a difficult concept, but some people may not be fully aware.
They are only sold as a package because that is how Subaru receives them.īefore going any further I'll give a quick rundown on how a short shifter works. As confirmed by Tom at Kartboy, the shifter itself is what creates the shorter throws with the SPT setup. I am calling it the SPT shifter to avoid confusion with the 6 Speed STI transmission. It is often called the "STI Short Shifter" and is sold via SPT. I also wanted to clarify that the SPT shifter is the OEM factory short shifter. Other models may have different dimensions. The first thing that I would like to point out is that these photos and measurements are for the 2008-2013 WRX / 2006-2009 Legacy GT / 2006-2008 Forester XT. I didn't see much like this online, so I hope they are interesting/useful to someone. I was curious to try some different shifters, and I managed to get the stock, SPT, and Kartboy all together at the same time, so I decided to take some photos and measurements for anyone who is curious. 08+ WRX 5 Speed Short Shifter Comparison (Stock, SPT, Kartboy)
