Two thoughts (more serious than my last post);

1. If it doesn't provide downforce (or lift conversely) then it provides drag. Aero(hydro)dynamics 101. You must have enough forward speed to realize the gain and not the loss (ie drag). An aereeeoplane traveling at sixty miles per hour (on land) will take less work to propel without the wings than with.

2. Why do we always bring up the "tuner crowd" segment? Wings are not keeping them away from sports car racing...access to it is, be it money or time or information or distance.
