It's still not a short THROW shifter. When you cut the top down, thats the only distance that is decrease. You still have the shifter that's under the shift point to contend with. When you just cut the top, you end up using more force when you shift. Your fulgrum point doesn't change and you need more leverage to shift. The B&M and Schnell shifter made are true short throw shifters. The shaft was cut down by 3" AS WELL AS changing the fulgrum point to make it a 1:1 shift ratio. Hope this helps.  |
When you cut down the knob side, you do reduce the shift distance, but not the shift angle.
The force you apply is proportional to the proportion of the distances on both ends of the fulcrum so whether you increase the rod side or decrease the knob side, as long as it's the same ratio, there will be the same force required to make the shift. The aftermarket shifters decrease the knob side AND increase the rod side, so they require more force than just cutting the knob side down. They also decrease the throw more.
