Hi folks has anyone done this before?

For 50 to 55 shore durometer elastomer it looks like they need to be molded rather than machined.
Also heat is an issue when that soft. So I am thinking Silicon rather than Urethane?
Can anyone point to a recipe for a silicone based highly damp compound I could use?
Target Vibes are 80-100Hz engine is 100hp and ~70kg

Also should I use a higher durometer for the lower mounts?

The design is essentially rear mounted with 4 two piece doughnuts and through bolts.
