Thats funny. I just found one of his videos on YouTube and was going to post it into here. I like the spring idea, but I think that this idea might have a bit cleaner look, since I can put it behind the grill if I want (probably won't though). Maybe a bit more adjustable as well. Then there is the whole thing about trying something original
I'm thinking I will attempt this in a few weeks after I put my Coroplast belly pan on. I will duct the air that passes through the activating vents down and under the car. Though I might want to duct in to the radiator instead. Trial and error will be the judge of that I suppose.
