Since tightening the bolts will likely be a bad idea because they are only held into the spoiler by fiberglass, I would say adding a shim layer between the surfaces would be the best route. There are lots of materials that would work, so go through what you have to see. Foam, modeling clay, sound deadening, rubber, some plastics, etc.
Thanks man. I have lots of deadening foam. Which is what I was planning on doing but I was just checking if there's something better out there that I'm missing.
