Other General
Regulations
All equipment is subject

approved by reason of having passed through inspection for any number of times.
If you have been using an illegal part or parts, for any number of times, and
have not been caught… Consider yourself lucky to that point.
For anyone caught with
illegal or modified engine or suspension components, there will be immediate
disqualification, as well as loss of prize money and points for that night.
For Major Rule Infractions; Illegal carburetion, throttle body, intake, or
exhaust, porting, polishing, tire treatment, stroked or long rod engines,
oversized valves, high domed pistons, clutch/flywheel assemblies, the driver
will lose pay for that nights’ events, as well as total loss of all points
accumulated at State Park Speedway.
These are violations that clearly cross the boundaries of our rules, and are
done to obtain an illegal advantage over fellow competitors. Any refusal to
comply with inspection requests may result in a suspension of the driver, car
and owner for three (3) consecutive races and a fine of $50.00.

final.
Ignorance is no excuse.
