That is interesting about removing the trans mount and having the vibration/noise improve. I may end up removing mine when all is said and done.

I also have “anti-wrap” spring perches that are quite long that I got from ruff stuff specialties (a local shop that makes some very nice axle swap parts). I probably don’t even need to add the 1 degree with those on my axles…. Regardless, I’m going to shim it and see if I get improvement at highway speeds.
