Unless you support the back of the flashing with a supporting frame...it's not gonna work as well as you think it should.

In this thread and in this thread, you can see the progression of my dropped air dam. Even the street sweeper coroplast didn't hold up at speed. It had a tendency to deform and fold under the air dam...and that was only 4" exposed at the bottom.

My current dropped air dam is holding up quite well and doesn't deflect at all...at least from what I can tell. It's all about the underlying support structure.
