that is not addressed within these rules the Chief Tech Inspector will render
the deciding factor.

discrepancy arises regarding any part/component or entire car being allowed
will be the absolute decision of track officials.
Any changes from the
car’s original OEM specs must be approved by the Chief Tech Inspector.
In the event that
any car and or driver has been competing with a rule infraction in the past,
regardless of the infraction or the length of time will have no involvement
with the tech decision if found not in compliance to these rules concerning any
tech inspection or protest situation.
If any disagreement
arises concerning part/component being OEM available at time vehicle was
produced then driver of affected vehicle must IMMEDIATELY produce the EXACT

Inspectors decision is final.
