I'm planning to install a B&M shifter this weekend. I've read in old posts that an older model had a habit of breaking but that the newest version has corrected this problem. I don't know if it will make it easier for me to find the gates (especially while on the track) but looking forward to shorter throws. This may be simple-minded but is there any additional effect on shifting with this kit vs. just getting one of the shorter knobs? I've read that some people find that the combo (short shifter and shorter knob is too short...not enough leverage). Also, the instructions indicate that you can either use their upper billet lever or the stock lever but there may be a little more vibration with the B&M lever due to no rubber isolation. Any feedback from anyone who's installed this product would be appreciated.
