I picked up a set of shifter bushings for my evo from Scott at TTP Engineering, two for the linkage at the tranny and the set of eight for the shifter housing itself. It was feeling kind of sloppy and I wanted to tighten it up. I am happy to say it worked better than I had hoped for.
The side to side movement has greatly decreased and it has a much more "gated" feel when going through the gears. If your car is getting older and feels a little used and abused from the daily thrashing, I suggest you pick up a set for yourself. For under a hundred bucks you can make your car feel better than new.
