Any idea of what they will look like Joe ?
That right there is the $64K question, right? I knew [MENTION=636]RAAMaudio[/MENTION] would be interested in seeing what emerges from this (and he got in here before I could finish my post). Personally, I like the thing that Team O'Neil runs (I think that's called the R5 wing that they source from M-Sport, although I'm not completely certain).
Some images of the well-documented wing:
And of course the Automobile magazine video (with a few fleeting views of the wing in action):

This is buried in my hidden "maybe" list, but that's a very nice price for the right wing. The R5 thing just requires the "stock" Fiesta spoiler as the mounting platform and some stout mounting brackets.
