The American Sprint Car Series has implemented a new rule regarding the top wing, allowing only one top wing for competition per race night.
The rule is directed at keeping costs down and ensuring a level playing field among competitors. The rule officially takes effect on Aug. 3, 2025.
See the rule description below:
Section 5 – Wing Specifications
- The same top wing must be used on the same car for the entire race night after presented for qualifying. The top wing that is used for the race night may be changed at the discretion of the American Sprint Car Series Director if the top wing has been physically damaged beyond repair for any unforeseen reason.
