While I find the results interesting, I'm just not sure.
On my previous car, Mission, I had an HPI Alfa shell which handled OK until during a race when the wing fell off. All of a sudden it woudn't go around corners at all. I had to back off round the high speed sweeper, it was a bit better around the slower corners (as you would probably expect).
I simply say this, if the body isn't utterly crap to begin with (speaking aerodynamicaly), then a wing is a necessity.
Having said that I have seen the odd car have the wing come off and it didn't seem to slow the car much at all.
