    You got it just right, seeing as where you live, your car IS upside down....well, to me anyway..

    The science stands: planes for aerobatics have a very symmetrical wing profile. Any wing can fly upside-down with the correct angle of attack, it's just that the drag increases.

    The theory as I understand it, is that the curve in the upper surface of the wing causes the air to travel faster over it creating negative pressure underneath; that makes an aeroplane fly, the bottom of the wing can be flat or even slightly curved either way, so for an aerofoil, to aid downforce turn upside down (of course aeroplanes can fly upside down making a slight mockery of the science!)

    I'm not either. I'm ok with the different surface length creating different airspeeds over each surface causing lift/downforce depending on which way up it is, beyond that.....further reading required

    I guess both are fine - I'm not an aero engineer but most drag race ones are concave on top (as is mine from Andy Robinson) so I assume the concave top provides more downforce than the flatter one?

    Ah, but the small Gurney flap on the back of the wing confuses the air into thinking it's concave.
    Anyhoo, I guess it worked well enough for Ralt!

    What's the theory behind that ?

    Flat seemed to work OK for the Daytona & Superbird...
