I also wanted to add the fact that a wing (a FUNCTIONAL WING) helps the rear tires get traction in ANY car, if a AWD car is used in a high speed road corse scenario, it would use the extra downforce to take the turns faster, because that essentially adds weight to the tires, and gives them more grip... And to add to the alluminum wing, all of our wings are mounted to the trunk, if the wing created anything CLOSE to the downforce created to HOLD the car down more, then your trunk would certainly cave in, i mean if you were to sit on a cars trunk would it not dent? Maybe not with Eclipses because of the hatch, but the same idea stilla pplies...
