I'm stealing all of
Harpo's ideas!
Here's a picture of the front as of today. You can see why I think I might need some additionnal front wheel air dams. You can also see the pipe insulator part gone awol in the 2nd slot from the top in the upper grill.
Here's a comparison before/after
The only problem I have with it is that the flat front part can easily be bent backwards a bit which might create even more lift. I can't see how much it flexes at 75 mph, but the sides are pretty strong because of the curve.
All in all it extends down 2 inches in the middle and 4 inches on the sides.
