Oh I definitely think its worth it (and I don't believe in spending the extra $$$ for brand name Dynamat) - adding it on the door panel is going to keep road noise out and sound in - which GTMat did you get? Ultra, Pro, or Supreme?
I had a roll years ago on my old VW Jetta and it helped a ton - definitely thinking about doing it "while I'm in there" when I do get to my E53 door speakers - for the $75 for a roll and having about enough to do 4 doors I'm fine with that .
