Shark Nose or Snow Plow?
That's exactly what I was wondering about and the advice I was looking for! Thank you! So what you're saying is, the air dam should be more of a 90 degree angle, instead of sloping to the ground as it is in the picture?
I was wondering about that. What is better; a shark nose type of bumper, or a straight, 90 degree, snow-plow type of bumper? I guess with the cardboard air dam you see, I maybe thought that having it angled would push the air under and over. I thought maybe that the least amount of contact of air with the cardboard surface, and less surface, would be better. Please tell me if I'm wrong ecomodding gods!
I suppose I thought it would be like a hang-glider or a parachute or bird wings, and I am afraid that maybe a 90 degree large cardboard flat surface would actually increase drag, and that maybe a more of a shark nose type of bumper, like a pointy fighter jet, cutting through the air, would have less drag. Which is better?

is the cardboard being held at the bottom too, because if it's not then in the wind it will flex and move up...i noticed my lawn edging was going up when driving on the highway which is not doing what it's supposed to...
Also try to angle the airdam so that is picks up the air over the car instead of at the ground
