I only test drove the car and I can tell you, I could hear everything from the rear wheel wells. I have already come up with a few ways I think I will go about reducing the road noise. I have read through the forum about stuff like rhino lining and sh*t like that, but that isn't going to stop the flex and reverberation in the panels. All that is going to do is add weight. I plan on using the 80mil DynamatX in conjunction with Second Skin's Overkill foam and Spectrum sludge. I am going to use the Overkill foam and Spectrum sludge under the wheel well cover, then on the exact opposite side (on the inside) I will put down the Dynamat the Overkill and the Sludge. If this doesn't work, then NOTHING will!! Not to mention a full DynamatX project through the whole car. I won't race or track it so I don't really mind the extra 75lbs or so.
Here's the site for the Second Skin stuff...
