A RACER DOES NOT OWN A RACE VEHICLE NUMBER IN King of the Kastle (KOTK). If a participant has a request for a certain number in a certain class KoK will do its best to accommodate that request. If the race vehicle is sold, the number does not go with the race vehicle unless approved by KoK. Vehicle numbers, once assigned to you, must race at least one KoK event during the season to retain the number. Sorry, we are changing the class numbers again, to become constant with other sanctioning bodies.


Race Vehicle Numbers

Each class has its own four-digit numbers, the first two numbers are the class, and the second two digits will be the car start position Example the first car registered for the Pro-Unlimited class would be 3000, the second car would be 3002 etc... 


You retain your numbers from the Fall race and as long as you race one KOTK race a year, and you don’t change classes, you will retain your number, year after year. 

6" Numbers on sail-plates on the sides and rear plates and 4" Numbers on the front edge of the roof  


Start positions for the June 3th, 2023 race start positions will be given in order your registration timestamp. Entry Opens February 1st 10am 2023 and CLOSES MAY 15TH NO LATE ENTRIES ALLOWED

Remember if you move up to the Pro-classes, you can’t move back down in class, so be sure you are ready to move up in the pro classes.
