[Floordford]

Varn extinguished an idea i had as i was reading this. My thought was to make a very low air dam on a hinge with a trunk lift shock or two. That way it would be dropped as low as possible for driving. It could scrape and move out of the way over speed bumps but then not do any damage to the unit. Then the shock(s) would push it back into place.

But if it makes too much frontal area to be effective then that ones out the window. Though I seem to recall a Dodge Ram with a huge air dam. Dont know if it worked out for him though.
