Ok all...I got my samples from Stock Interiors. The pics below are the comparison between standard carpet backing and "Mass" backing. The Mass backing sounded good to me because the girl over the phone said is was better road sound deadening (which I really don't mind), but more importantly, insulates the floor from heat. I though that was nice, because i don't have AC and the floor does get hot, which does radiate through the cabin. I was concerned though, because I knew that the thicker backing may be difficult to wrap around the sill lip and wind lace. In the pictures, you will see my test. The black looped standard carpet was just like the original screwed in nicely, buy the Mass backing was a lot more difficult and I'm not sure how a full carpet install will work around the sill and B piller trim. I was able to screw the sill plate down, but it was tight. I was disappointed though, because the pile of the Mass backing sample, was not the loop 80/20 style like the other sample, so i don't know how the 80/20 with mass backing will be. I also have a closeup of the two to show that the 501 backing was semi-porous (little holes) and the Mass backing is very solid. Any of you guys have an opinion about moisture retention with Mass backing made that way? Big John, any thoughts since you were in the business? The girl on the phone said no but, I'd like to hear what you guys think. I hope this and the pics help you guys that are inquiring for a carpet as well!
