OK, I can see my idea/error that the GroupN tranny mount was the whine culprit since I added the Tranny mount, cross member bushings, STi SS, and the same shifter bushings as you, all the same day. I put the GroupN rear shifter bushing in initially and never swapped to it (as you swapped in the N to lower the whine). I recall the biggest difference in any of the bushing materials was definitely the cross member bushings. I dunno if thats any evidence for the increased gear whine or not. Its just not that bothersome for me to swap them out and see.

Yes, gear whine is my only complaint. In 1st and 2d gears primarily, but its livable in an STi imo. I still need to install rear diff and subframe bushings, but I'd like to avoid any NVH.

Congrats on the underside of your car, seriously, not everyone puts a priority on it.
