Off of the back of the exciting announcement of Auto Value coming on board as the entitlement sponsor of the Owosso 500 Series, and with eager interest from teams, Owosso Speedway has announced the early open of registration for the Shiawassee Humane Society 100 set for May 17th, 2025.
With this extended window drivers will be able to request which chalk marks and how many sets they would like on hand for the event. Please note drivers CANNOT choose a second set until after ALL teams have chosen their first.
Drivers are encouraged to register early, as this entry form will also serve as the tire order for the event.
Registration can be found at: https://www.myracepass.com/tracks/2289/registrations/10764
