With that bit of literary excrement removed, in went the CNC aluminum Kartboy unit that uses urethane bushings. The pitch stop mounting location is directly on the top back side of the motor where the transmission mates to the block and as such this modification improves shifting performance by reducing rocking under load. Because we are in the process of other modifications the top mount intercooler was already off of our car and this made installation of the Kartboy stop a two bolt affair!
We next turned to the underside of the car where we used the Kartboy urethane shifter bushing combo. This kit replaces the front rubber bushing and the rear stay bushing with higher durometer urethane bits; decreasing slop and providing a more direct shifter feel. With these items in place one can really feel the shift engagement as well as the stiffness provided by the combination. The Pitch stop definitely transmits more trans noise to the interior however it is perfectly tolerable in our opinion and in the case of a car like the STi we rather like it.
The last drawback that needed to be addressed was the OEM shifter and in order to ditch that we turned to our Aussie friends at Go Fast Bits. Their short shifter is SUPER trick in the way it works and how it is adjustable! You can shorten the throw to your liking and in addition you can use their mounting brackets to preserve the proper fulcrum point to reduce bind and decrease that notchy feeling. In our case we wanted a nice solid feel with slightly shorter throws and yet did not want to increase the shifting effort or make it hard to find specific gears.
