I've got an EVH Wolfgang standard with a down only floyd rose. If I play unplugged loud enough the bridge rattles. If I've got the guitar laying flat the weight of the bridge is enough to stop the rattle. The only thing I changed was a height adjustment to set the action. I don't know if it rattled before this.
It looks like it's sitting on there pretty flat, but that could be the only problem I'm thinking.
