is this the same Perrin short throw adapter that the WRX uses? It sounds exactly as the same install as the WRX model.. I loved my Perrin Short Shifter Adapter. It is definitely an easy install and easy to adjust. One thing that it doesnt do that an STi shifter can do is the side to side distance reduction. The real terms for "shift" and "throw" is that "throw" is the distance from moving up and down on this shifter, while "shift" is the distance from left to right.. not sure if you all knew that terminology.
