I just got my shifter base bushings and
 

They are amazing, My shifts are more precise they feel so smooth. I got them from corsportusa. I highly recommend buying them and if you haven't already bought a short shift adaptor , and aluminum cable shifter bushings to get those as well. You can get all three from corsportusa.com great service

I have the TWM stage II short shifter and the base bushings and yes they are pretty sweet!

Ya they are so smooth compared to how it was before. At times I wasn't able to shift into 2nd and 3rd without it grinding and once i switched the cable bushings out and base bushings that totally eliminated my problem, Now im looking to either go suspension or save up for a full race turbo kit

I did the short throw adapter and bushings as well, shifting is indeed more precise and feels closer to the older Civics with mechanical linkage (versus new garbage with cables). Driving is actually a lot more enjoyable with those two little mods alone.

that says something because civic w/ linkage feels rubbery. lol

so it really makes a difference
