The Winged Sprint Car as you can see looks a lot different than the dirt Sprint Car. The chassis is a lot lower and cleaner looking. It is lower because it doesn't need as much suspension going into the corner the dirt sprint cars need a lot of suspension because they are so far sideways by the time the car enters the corner they need a higher and more efficient suspension. The Asphalt tires are a lot different also the asphalt tires are more flat surfaced and small wide and the length wise. If you were to take a dirt car and race it on the asphalt one, they would look really weird and it would be pretty hard the dirt and asphalt are extremely different.
