I've got no clue, whatever was there is still attached to the bottom of the carpet in a box. I think its just some extra padding around that area IIRC. I can take a look and measure...
No need to measure. I didn't explain myself correctly. A lot of the carpet in the car has a very dense foam backing (cheap MLV). I just wanted to know whether what you removed was merely carpet or foam backed carpet.
I'll take my remaining 6 square feet of Luxury Liner Pro and spot treat that area when I figure out what kind of material is located there. *writes self note to buy another sheet to treat the front doors*
I know that this is not what you would do, but I'm working hard to carefully mitigate noise without adding excessive weight and I'm working to counterbalance that with weight reduction mods. Next up is a Deka ETX20L battery, which is 26 pounds lighter than current 78N battery. 3795 pounds and falling!
