Solid Rear Engine Mount?

I'm new to the forum and a new ST owner. I am a mechanic and I understand the correct way to do things. I have access to lathes and a Bridgeport. I can make my own mount. Just wanting to know opinions about making a solid mount. It seems like one of the first upgrades people do. I can see why as when I shift hard I can feel engine movement. Should I venture into making it solid? Yes or No? Why? Thanks
