Interesting paper.

The red looks better than the blue. I don't know why the square back and notch back are so different, very strange. The blue defiantly had more air flowing, because of the bigger opening.

I don't think this paper applies completely, since my wheel wells are covered the air can not escape through the sides, but must exit under the body through the tire clearance holes in the belly pan.., my grill opening is minimal, I will be keeping most of the blue closed.
