I have one on mine. The throws are greatly reduced, but effort is increased. Sometimes I overshoot 3rd and get hung up if I'm trying to shift too fast. There's a spot between 3rd and 5th where the shifter will get stuck and not slide into either gear w/o going back to neutral. Seems there's some slop that wasn't there when stock.
Overall, though, I'm pleased with it. I wouldn't go back.
