I have the Supra Sport SS shifter installed, however I bought it before they had come out with the shortened shaft, so it is still stock height. My brother has the SOGI SS mod done, which is shorter shaft but not throw. I like the lower feel of this better and was wondering if it would be safe to saw off part of the shaft so I would have shortened throw and height. Didn't think this would negatively affect anything but just wanted to make sure. Also I have an aftermarket knob so don't care about having threading since it is attached by screws.
