I drove my rommate's '97 T/A WS6 before and after a Pro 5.0. I was really happy with the feel of the Pro 5.0, and was actually looking for one for the fox, but I was looking at $100-150 for a used one. I couldn't pass up a new Tri-Ax at $100.
I've driven a couple m/t fox body and sn95 cars. All of them have had a really sloppy, rubbery feel to the shifter. Even the T/A stock shifter was slightly better than most stock T5 shifters I've driven with. In addition, T5's don't have internal shift stops, so bent forks are fairly common from overaggressive shifting.
There are basically three big name shifters for T5's: MGW (supposedly 'the best'), Pro 5.0, and Steeda Tri-Ax. After doing some research, everyone loves MGW's, and there are very few complaints about the latter two.
When I get the car driveable, I'll let you know how it feels. I still need to pull the roof and bumper off a donor car here soon, so it's got at least a month before I get it on the road.
If you want to pick one up, I got it from
www.stangsuspension.com. It appears they still have one left.
