If they were "Energy Suspension" mounts purchased over the internet, they could have been 'gypo' parts made in China made out of who-knows-what??
If you have a well balanced engine with little vibration, go with solid mounts. If you have a stock engine, install the stock rubber mounts. Either will solve your problem.

on a C3, remember that the body is isolated from the frame: the body has rubber bushings for mounting to the frame. this means that vibration, noise on the frame is not transmitted into the cabin. So in the case of the C3, use of steel motor mounts does not result in a whole lot of engine noise, vibration being heard or felt in the interior of the cabin.

wow, I didn't know that, good to know, very interesting. I have a 78 and a 75, so both with rubber body mount cushions. I would think that the aluminum mounts would have a corrosion problem. Thanks for the correction.

I have solid mounts here too. Reports of melted Energy Suspension poly engine mounts are why I bought solid ones when I already had the poly on the shelf ready to go...
Yes. But it made very little difference compared with when I was running rubber mounts, where the spreader bar made a huge difference. The solid engine mounts definitely help to stiffen the front of the chassis. I put the spreader bar in when I had the original engine and mounts in the car and it made a huge difference. I took it out when putting the new engine in with solid mounts, and drove it for a while before putting the spreader bar back in. Much less difference, almost negligible when adding the spreader bar with solid engine mounts fitted.

Speaking of an engine being an integrated part of the suspension....
