Aero guys...talk to me about the Impul wing.

As far as 'working', it's just a guess. You'd have to put them in a wind tunnel to see for sure. There is so much going on before any air gets to the wing that the aero engineering has to be spot on. I figure for most wings it's about a 33% chance it hurts, 33% chance it helps and a 33% chance it does nothing. With aero, it's a lot easier to be wrong than to be right.

And remember that a wing vs. a spoiler accomplish different things- a spoiler is all about downforce where a wing is downforce + stability. Take a look at how the wings are set for qualifying at the Indy 500 - they actually tilt them back about 10* to take away downforce. But if they just took the wing off the car would be undriveable because you would lose the stability the wing provides.

Not really. A spoiler doesn't provide downforce. A wing provides downforce, a spoiler disrupts the airflow behind the car to reduce turbulence or drag.
