- NO WHEEL CLEANING!
- All cars must be gravity powered.
- No work may be done to cars once they have passed inspection. All cars must go from the inspection area straight to the staging area.
- If a car jumps the track it will be disqualified from the event. The heat will not be rerun unless the infracting car makes contact with any of the other cars in the race or if it found to be an issue with the track.
- In the unlikely case of a car getting damaged, reasonable repair can be made to the car as long as it is ready to race again by its next heat.
General event rules and considerations
- Please use caution around the facility. No running or climbing over the track allowed. Stay behind any taped off areas.
- Do not pick up or touch anyone else’s cars without permission from the owner.
- Anyone and everyone is welcome to come but due to limited space please leave small children home if possible. PLEASE BE RESPONSIBLE FOR YOUR CHILDREN IF YOU BRING THEM! Please keep them from the car staging areas to avoid any unfortunate accidents.
- All cars must pass inspection before they can race. All decisions by the inspection team are final so please refrain from arguing or causing a scene if you disagree with an inspection decision.
- This is a family event and even though it will be very competitive please conduct yourself in a proper manner refraining from vulgar language and inappropriate behavior. By all means cheer and have fun! This is a race! Please avoid the embarrassment of being asked to leave the event.
