How do you test front/back wings for autoxing?
take them off, and see if you go faster or slower!
seriously, though, FSAE has done some significant work in this area. likewise, i've seen data aquistition on the web that shows those cars doing .4 lateral g's
more with the wings than without. the question is, of course, is: given the added weight/higher cg/etc., does this result in a faster net time? one would think that the Amod guys have already answered this.
low speed aero is real, it's just a question of whether or not it would be a net benefit given the car and the layout of the track.
