Never had any problems in an FB, just made some for my FC. We aren't using the engine as any kind of stressed frame member which is a big no-no. It sure makes it nice for throttle steering in long turns, no mount flex to wind and unwind.

I believe in using the hard polymer motor mounts that Mazda Motorsports used to sell. I use a hard polyurethane mount for the tranny. Both still allow a very slight amount of flex.

Solid mounts put more vibration into your chassis, and if your chassis isn't perfectly rigid (nobody's is perfect,) then you stress your motor housings & tie bolts.
