NOTE: All of the Factory Tracks rules are subject to change without
notice and are at the sole discretion of the event officials.
Additionally, we DO NOT want to turn the series into a “rule
nightmare” the intent of the series is to have fun and be competitive! So
please do your part and don’t stretch the rules.
General Rules
The general rules will be covered at
the driver’s meeting before each event.
We will be using
“Live Wire” starts for all qualifiers which means that the drivers must be on
the track and checked- in before the two minute clock expires and they can
start at any time after the official race director starts the race. Once the
race has started and a racer has logged the first lap any racer starting after
that time will be at least one lap down.
“A” mains will be 30
minutes with a mandatory 2 pit stops.
“B” mains will be 15
minutes with a mandatory 1 pit stop.
All other mains will
be 6 minutes.
All Main events will
be “flag starts”
Note: If any vehicle
has to be returned to the pits for repair or a restart that will be considered
one mandatory stop.
