To be invited to the World Finals you must:
Attend at least one divisional points race.
At the end of the season you must be in the top 16 competitors in your class, in your division.
So if you had 16 qualified vehicles in all 5 classes in all 6 divisions you would have 96 vehicles invited in each class, thats 480 competitors invited to the dance.
Vmax, We will have a race in LA again this year at No Problem, if you make 2 of the 4 races and place middle or better of the field, good chance you would make the top 16. What class are you looking to run in?
