AZNP Classes & Rules

Arizona No Prep Racing has the final call on cars in these classes— If a car is questionable, a three person committee will be consulted and a vote will be held to see if the car fits within the spirit of our racing classes. There isn’t a perfect solution for rules, there are grey area cars. If you have questionable car please Contact Us. Especially Medium and BIG TIRE!

We have the right to refuse any car that’s why you should ask first. We are a small No Prep Racing family and you will not find a harder working group of people that wants to be fair and wants this type of racing to continue and thrive for the racers, and the fans!
