Odd. I have the Fast Intentions flex plate VR30 7AT and Godzilla driveshaft. I’m using a stock type poly trans mount from Z1 with a modified chassis mount. I have no noticeable vibration.
If the driveshaft was balanced properly and you had it checked you could swap another known good driveshaft to see if problem persist.
Or check that trans mount. Maybe some resonance frequency vibrations going on.
