     General Rules -

    Penalties will be issued for not being on the track to Marshall. There are numbered tubs on the track. you are required to place your car and radio in the tub and marshal by that spot. They are number 1, 2, 3 etc. if you start in position number 3 then you are required to be marshalling in tub 3 area. There are no warnings - if you are not in tub 3 area at the start of the next race your best quallifing time will be disqualified for the day. If you are unable to marshal, you are responsible to have some marshal in your designated area.

    All oval Cars are rolling starts. Electric Mains are also rolling starts.

    No car will be driven at any time in reverse of the track traffic. If this occurs, a one-lap penalty will be deducted off the driver’s best time. The use of reverse is illegal in all classes.

    Turn marshals may not work on or repair cars.

    It is the Drivers responsibility to bring the vehicle to the Tech table immediately following your turn marshal duties. Failure to do so will result disqualification.  

    Any violation must be corrected BEFORE the car is raced. If a car passes through "Tech Inspection" and a technical illegality is over-looked, the vehicle is still illegal.  

    Any racer may front $50 for tech inspection for any car on the track - if the car is found to be legal the $50 will be forfeited and given to the legal racer.

    Tire Rule and Tech Procedure

    We are a paragon free facility. Paragon or tire additives with wintergreen oil will not be allowed. Previous paragon odors can be removed with HOT water and dish detergent. You may have to do this a few times. Tires will not be allowed to smell of any type of mint. All tires must be wiped completely clean with a cotton rag and go through tech, even prior to practice. If a car goes onto the race track without passing through tech that car will not race on that particular day, regardless of when this occurs, including practice. If your tires are not wiped dry to my standards, I will wipe your tires clean with a rag prior to being placed on the race track.

    1. All tires must be dry.
       2. All tires must be completely free of any mint odor.

Class Rules

Sportsman Latemodel and Sprint Rules

The intent of this class is to reduce the costs of racing by reducing the need for a speed tuned motor, expensive battery or a variety of tire options. This class will only be available for the racer who wants to put fun back into their racing – want to show up and have a good time without worrying about the motor dyno? Then this is the class for you.

Drivers who ARE NOT eligible for this class include anyone who is currently listed on any of lists currently used by the WDRA/USOWC etc. as well as drivers who receive factory sponsorship or racers who have a known ability that exceeds the intentions of this class. If you have to ask me “Can I run this class?” the answer is probably no.
