2023 HORNET RULES

 

 

 

The goal for the 2023 season is to continue to build the class and bring it back to a true entry-level class with a focus on affordability. The emphasis is on keeping this class of cars
inexpensive to build and run throughout the season while providing a high standard of safety.

 

Please review this year's revisions carefully. All of the revisions are highlighted.
It is the driver/owner’s responsibility to ensure his/her vehicle is legal. If there are any
questions about the rules, contact the tech director.
Non-conforming cars will not be allowed to compete. Minor variations may be approved at
the discretion of tech staff only. We have attempted to build allowances for those cars that
have pushed the envelope in the past without forcing sizable expenses.
2023 will see the Hornet class rules strictly enforced to regain close competition throughout 
the class as well as respond to safety concerns associated with the speeds.
2023 Will also see DOT tires brought back to the class. There WILL be a transition time to
allow for the current race tire inventory to be depleted. In an effort to minimize potential
losses to all parties and maintain a competitive field. 2023 will see a blend of DOT and Race
tires allowed as outlined below. 
Penticton Speedway is in negotiations with several tire manufacturers to test and secure quality inventory with pricing to match.
 

● All cars running over 16 sec. MUST weigh a minimum of 2,300lbs with the driver.
● Any car running under 16 seconds lap times during practice, qualifying, or race will
be disqualified from the competition and all results and points will be nullified.
● Any car with a minimum weight of 2,700lbs with the driver will not be subject to the 16-
second rule and will be deemed legal and awarded all results and points.
● Any car utilizing ballast to attain the minimum weight of 2,700lbs must locate 200lbs of
ballast in the front seat passenger area of the car, on top of the floor pan, and clearly
visible to tech. The other 200lbs can be secured where teams see fit
● Ballast must be adequately secured in place.
Penticton Speedway may change the minimum weights at any time to ensure parity between the
two weight categories of cars.
The final decision of the Track Officials and their interpretation of these rules will be the final ruling.
These rules are designed to keep the Hornet class an entry-level class.
