As far as performance goes, it will depend on the situation. As with any air flow modification, at low speed all your doing is carrying extra weight and creating extra drag. At high speed, when the airfoil is functioning it will create down force and drag as a result.
For high speed freeway, road course, canyon runs, and other generally constant high speed driving it should help performance, not necessarily in a straight line, unless your getting traction issues at 60+ MPH. Where it will shine is when your doing over 100 and turn. It should help stop the front of the car from pushing out so much, allowing you to maintain speed in the corner.
This of course, is all assuming it was adjusted at the correct angle on the front of your car. For straight out 1/4 mile performance, I would say no change whatsoever unless, as I said, your putting down a lot of power and loosing traction in 3rd gear and beyond. There are plenty of SRTs that have traction issues into 4th gear and some in 5th, so it is definitely application specific as far as performance.
Yes, if it is adjusted properly it does provide a very significant amount of down force, enough that one customer noticed that the lip was dragging on the road at 130+MPH, meaning it pulled the car down at least 3 inches.
