I was thinking the same thing... The shafts no doubt get pushed and pulled as the engine rocks back and forward? Also just vibration I'm general. The solid mounts would take away from the hubs. But would still find its way back to the parts and losen parts regardless.? I just didn't used enough threadlock I suppose and the parts haven't settled since the rebuild. I reckon I could whack this stuff up again and it will be okay. I find my engine is hammering around the engine bay on gear change and heavy foot work. I think I have a dent on the slam panel and firewall. Solids will need to be thought of.

Matt does a set that i have but iv drilled them out as well as they were just too stiff. Would be fine for pure rally / circuit but i like having a Sunday drive as wasnt keen on the constant buzzing! As you say potential for loosening of parts.
Maybe worth having a look at the polyurathane / rubbers you can pour into an original mount to stiffen them up?
Il be doing this with my rear engine mount when the engine next comes out
