I installed this shifter with the solid bushings on my Integra Type S and it's been such a great mod. It takes about 45 minutes to do the install from start to finish and it was very easy to do. After tinkering with the adjustments I found the best settings for myself. I'm on the shortest throw settings and the default gate settings.
There's absolutely no slop in the shifter and the shifts are crisp, quick, and smooth. The factory shifter was already really good but I felt the movement was too light. The K-Tuned shifter adds some much needed heft to the shift action but not an excessive amount. Just enough to feel engaging and doesn't take away from the driving experience. Moving from gear to gear also still feels factory smooth and not clunky, despite requiring a tad bit more shift effort.
The shorter throws allows me to get off and on the throttle quicker so I'm better able to keep up with day to day traffic. I don't track but I'm sure this would make a significant difference for those that do.
All in all, I'd recommend this short shifter if you're looking.
