Speaking of oxymorons, you guys are absolute morons.... Any wing that sits above the roof line is functional. It keeps the rear wheels planted.. when I drag the car the wing will be off.. when I road race it and on the street, it is absolutely necessary. They even explain it in one of the option 2 video's and show a split screen side by side comparison of the car with wing on and wing off on the road course. Without it the car is all over the course.... with it, it's firmly planted in the corners. I guess if you're car makes no HP "you" don't have to worry about that.
