Thanks for the images.
Since the context of the photos is 'auto-crossing',then I'm presuming that the racers are trading speed for downforce (since highest attained speed in autocross is relatively low in comparison to other track racing).
Every example shown would incur a MPG penalty.Careful 'tuning' of size and angle could achieve a drag minimum at zero-yaw,but in a crosswind the benefits would be dubious.
For $2,000/hour,at Lockheed-Marietta you could find out.Eventually.
