i have been thinking lately about air dams

they reduce the amount of air going under your car (which is a 'dirty' place) but I also think they create a higher pressure in front of the lower bumper. What if we made V-shaped air dams. they would have a point at the very front edge of the bumper and wedge off to either side and stop at the outside edge of the wheels. it might be better or it may have more drag than regular air dam because of friction with the iar rubbing on it. i don't know, just a thought. let me know what you think.
