What kind of foam did you use?
I honestly don't know...I got it from work. It's pretty dense so its not very flimsy.

Thanks for the explanation Kevin! Very useful to know that the air dam actually pushes air down and not up. Now I'm wondering why a local fox body road racer told me air is pushed up???
I did a yarn test ( and video'd it) in which i attached yarn near and around the air dam. Even at 10mph all the yarn was directed under the car. Up to 80 mph not one strand was ever moved in the upper area. This test was done on my 2004 cobra.
