Hey Guys, chasing those rattles can take alot of trial and error. I have dyno matted the entire bottom and back (interior and exterior of where the tailights go), top of the trunk lid, removed my rear bumper and done along those edges, and I still am getting rattle from the tail lights and even more from the pedastal spoiler. I think I have spent close to $500 in dynomat.
Goodluck, let me know if you find a better way to keep those tail lights from making noise, perhaps using some kind of a foam would be better.
