What are pitfalls of "hard mounting " tranny vs rubber mounts?

Noise, Vibration, and Harshness
If you have ever run a car with a wrecked trans mount and the trans sitting metal on metal, well there is alotta lotta racket and vibration sent into the floor. And on every shift POW!

That's a nice looking mount tho,
and I'm wondering about the two downlegs, below the hoop. Are those biscuit mounts?
But if you are keeping the T-bars, I see your point, you would need a massive hoop to pick up all the points. Have you considered suspending the trans from two side mounts? Or a top mount even...
There's also no reason you couldn't divorce the mount from the T-bar hoop and move it back further to the rear. The tail is aluminum right; you can weld a bracket on wherever.
Careful not to run out of seat-rail space,lol.
Yeah I see a bit of thinking time for sure. I'm very interested to see how this all plays out.

At this point I am looking at suspending from the four side mounts, the engineer geek in me says mathematically they will be more than sufficient. The racer in me says I am screwed if I do not go rubber mount. On plus side I am very handy at welding cast aluminum so I am going to mount it hard watch it close and regroup if she breaks. I am building car for wife and she typically doesn't thrash them like I do although she is not above donning a helmet and dropping the hammer at the track! Did I mention she drinks beer and loves to camp in a tent and hunt deer and elk for days on end? And she fishes better than I can? Oh yeah love me a redneck girl! And she patches me and the boys up after hockey games when we try to do things only young hockey players should do. All of which is why I am building the Demon for her as a daily driver.
