A few weeks ago I took the window out while replacing the lock assembly.

When I reinstalled the window, the twisting was the worst ever until I slid the SBC bracket as far toward the door hinges as possible. No more twisting, but now I get a little wind noise on the highway. There is also a worrying "thunk" as the window completely closes that makes me think the top of the window is not aligned properly with the upper channel. Seems to be a fine balancing act.

I would have kept trying to find the sweet spot, but there is so much slop throughout the entire regulator assembly that I was left with the impression that it is just plain ol' worn out. (Lots of speculation on my part since this is the first time I ever played with "door guts.") Once I have time to mess around with it again, I intend on comparing it to the passenger side regulator before I actually start shopping for a replacement.
The guys at my garage want to experiment with this same idea since they shared your observations (mostly that OEM tracks are crap even new out of the box) the last time I had it in the shop. Their idea is to leave the SBC bracket in place, but glue a tire weight or two to the part of the glass closest to the B pillar / door jam to keep the glass from leaning forward. We'll see how it goes.
