I've been thinking the same thing. For me, it's mostly road noise. At first I thought it was just the Goodyears that mine came with, but it seems like other people with different tires seem to think the same. I'm going to be getting different tires (either Nexen or Conti) when I figure out which aftermarket wheels I'm going to put on and I'm hoping it doesn't get worse.I feel like most of the noise comes from the wheel wells, wonder if lining or spraying those would help
For the vapor barrier I used a fresh razor blade and cut it in half as I pulled the barrier away from the car. This made removal easy compared to just trying to pull it off. When I tried to pull the barrier off it would stretch and tear sometimes instead of coming off...lolI was ready to line my doors but it was about 45 degrees and that vapor barrier would not budge so I am waiting until spring. I don't think I want to deal with the floors though.
