Any ideas for an airdam?

I was wondering about the slant. IMHO it would seem that a rearward slant would be better than a forward one. The flat might be a middle of the road option but the easiest to pull off.

I do like the under body fairing but don't know how to make one that would survive a New England Winter. I have dragged the frame over a many a snow bank. Flexible airdam and side skirts are a must.

Wow. Those actually look really good! XD (Better on the Volvo!)

I'm actually going to do that myself!

Try an alunimun reinforced belly pan a'la someone on this site whose name I don't currently recall. Search "belly pan build" and you might find it.

About the slant: A rearward-leaning air dam would force air downwards, resulting in lift. Not good.

A forward-leaning air dam will force air upwards, result in downforce. Good.

For every action, there is an equal and opposite reaction. Push air up, you go down. Push air down, you go up.

With a flat air dam, some air would be pushed down, if the bumper above the dam sticks out farther than the dam itself, because air flowing upwards would be stopped by the bumper. More air would flow to the sides than anything, though.
