One of a mini sprint as well as the larger sprint car’s most distinguishing feature is its wing. Large sprint cars have huge 5ft. x 5ft top wing mounted while a min sprint car has a much smaller wing that is at maximum 16 square foot and the nose wing smaller as well at six square foot. Regardless of car size and wing size they are well in proportion to the cars and this is making a huge handling and performance difference to the sprint cars.
A mini sprint car use small front wings or nose wings that balances the car as well as keeping the car’s front planted onto tracks. Even though it has not always been a part of mini sprint car racing it only appeared in sprint car racing in the 1970s. Professional sprint car racers noticed the major handling and performance gained by using these wings on their cars and today you will not find one without its wings.
Aside from those advantages does it also provide opportunities for signwriting on the wings and also acting as protection in a crumple zone when the car rolls. Non-winged sprint car racing does exist however this is more evident in the USA’s Mid –Western states with the rest of America and the world running with winged sprint cars.
The wings work and acts as upside down aircraft wings would, as instead of lifting. The down force caused by air pressure differential between bottom and top wing surfaces are why the wing works so well to keep the car stable on the road the faster the wing moves the more air volumes increase which makes the down force even greater. The angle of the wing is just as important as the wing itself, but at the same time take note that down force is greater depending on the angle but also the aerodynamic drag. Thus if you want an optimum angle make sure the angle is around 22 to 24 degrees.
