But there are a couple of parts on these winged sprint cars that some race fans probably take for granted and really don't give much thought to as the dust flies and the dirt wallops the fans with every passing lap. The one on the front mounted just ahead of the front suspension puts down force on the front wheels and helps make the car turn in the corners. The large end plates also act like the feathers on a dart, helping the car stay pointed in the right direction and keeping it from getting too far sideways. Another benefit of the end plates is the advertising space they provide for sponsors. This is especially important when you consider the difference between the cost of running a sprint car and the typical prize money at most tracks, no one makes a living on their winnings alone, not even greats like Steve Kinser.
Most racers think the aluminum wing adds valuable crushable structure.
Cushioning the blow when a sprint car turns over, has saved many drivers from serious injury. It is for this reason alone that non-winged sprinters are banned at some tracks. There's no denying that winged sprinters are fast. Watching these cars run in humid air is an awesome sight. With contrails following the racers down the straights and the engines straining and roaring against the aerodynamic load, you want to hold your breath until the very end of the race.
