I used RAAMat and RAAMat Ensolite on the interior floors and doors/sidewalls and ceiling of my Formula to reduce vibrations/resonance. No scientific way for me to say how much it helped but as I installed it, I could bang on the floors with my hand before and after and tell the difference. It also kills the resonance of the metal in the doors so they close with more of a dead thud like newer cars. http://www.raamaudio.com/
