I have upgraded motor mounts, tranny mount, cf drive shaft, diff brace, clutch, and flywheel.
Any ideas?

No issue.
I have engine mount, trans collar insert, diff outrigger inserts, CF driveshaft with no issues, when I installed rear subframe bushings at 70mph it felt like a washing machine, removed rear subframe bushings and back to zero issues.
Have an auto so cant comment on clutch/flywheel. But could be the total accumulation of everything. I know plenty of people have no issues with the subframe inserts but most don’t have the other drivetrain mods i have. So i figure it was just the straw that broke the camels back so to speak.
Do you have LW crank pulley by any chance? Ive heard people having issues with having both LW crank pulley with LW flywheel.
