Well, I got my MGW shifter, BF bracket, and WL bushing all installed this weekend. What a difference! I'll stick to some observations on the bracket here.
It's a very nice piece, and installs easy. Since I did both the shifter and bracket I cannot speak to how much each contributes to the end result, but it does feel a whole lot more precise and "mechanical" for lack of a better term. Shifting is smoother and thus far on the street I have not gotten the 2-3 lockout. The 5-4 and 3-2 downshifts are buttery smooth, too.
One issue I ran into is the MGW heat shield and BF bracket. Note that this is for the current 2014 version of the MGW shifter. They simply won't work together. I did drill out some holes to clearance the locating bushing and got that all bolted together fine. The issue arises when you try to get the top half of the bracket mounted to the lower half. Because of the nuts holding the bottom of the shifter box, the heat shield stands a little off the base of the box. This means there is not enough room the get the BF bracket high enough to mount. I removed the heat shield are tried again. BTW, mounting & removing that shield is a big PITA since you cannot have the box mounted to the chassis. Once I got it all back together the problem became obvious. I could see that the bracket mounts in direct contact to the bottom of the shifter box, with the rearmost stud poking through the triangular cutouts. You would have to remove so much of the heat shield to make it work it isn't worth it.
I had to borrow a camera, so don't have pics yet, but I did try and take some to illustrate the problem. All that said, without the heat shield mounted, they play together fine.
