Thank you everyone for your input and feedback.
I have previously sucessfully used conveyor belt (baling belt from TSC) for my front air dam. (
http://ecomodder.com/forum/showthrea...tml#post453541) It works very well and is quite stiff when it is curved in one dimension and rigidly fixed at the top. It does not deflect even with my relatively minimal curve on my air dam on highway/interstate speeds, so in even sharper curves I would not worry about wind deflecting the fairing. The conveyor belt does have enough give that it would give if it contacted a rigid object to deflect and bounce back, so no real need for hinges.
I did some rough sketching in Sketch-Up, and attached some renderings of a front tire and fairings. Hopefully this will be more clear than my poor sketches in the first post.
