Downforce happens because the wind (air) is pushing down against the spoiler. That is why spoilers angle up, as to catch the airflow and force it to move upwards...thus pushing down on the rear of the car.
A spoiler that is "wind-adjusted" is just weight on your trunk. That is the only traction aid it would give.</td></tr></table><span id='postcolor'>
nope, you're wrong, the force is not generated by wind hitting the sloped the wing, but rather the different wing velocity on top/bottom of wing that generates pressure difference...
by Benulli's eq, higher wind speed creates "vacuum" like condition which cause pressure to drop on that side of wing. See how airplane wings when taking off have opposite shape of racecar wing, so instead of "lift force", gt wings create "down force".
the ebay scam could make sense, depending on the pivot point of the wings... shifting of the wing is by wing force tho.. or drag..
sorry for talkin like a hardass, really gotta get my mind set for summer fellowship..
