I like my B&M. If you have been reading about the problems some people have had with bolts loosening, etc.. I have circumvented most of that stuff.
First, Loctite everything together.
I have also used bolts with the proper threads to secure the lever, (stick) to the shifter. I used nylock nuts on the back end of the bolts to prevent them from coming loose. The funky screws they give you look nice because the are countersunk into the peices, but I believe that the flared shoulders on them contribute to the problems people have had with them backing out.
I recommend drilling another set of mounting holes on the stick that will mount the stick so that the knob sits lower in the console. Mount the stick on the side of the shifter that is closest to you. Those two changes position the knob much more to my liking than if you just put it in the way the instructions are written. Suit yourself, though.
The only real "Problem" I have had with shifting, is that when I went out with the G-tech to practice for running @ the 1/4 mile track, I had problems finding 4th from 3rd on a hard run. I think the fact that I had just driven over 240 miles home from Seattle and the car/trans. was hot was more to blame than the shifter, however. I was pretty tired at the time as well. I have since discovered that I am not the only one who has had that problem, I don't think all the parties discussing it had the B&M shifter. I think it has more to do with the trans. and possibly the fluid used at the factory than anything else.
Overall, I'd say 9.5 out of 10, with the way I have it put in. I have had some people say that the pattern is pretty tight, but when you're bangin' gears, it feels pretty good if you ask me.
