crew members) a manner designed to minimize to the degree
possible the risk of injury to themselves and others.
The rules in this division
are intended to make racing less expensive and keep
competition equal as possible. While these rules offer a
good outline, every item cannot be covered by a written
rule. If you come up with something not covered in the
rules, PLEASE ASK FIRST!
No equipment will be
considered as having been approved by reason of having
previously passed through inspection unobserved. No car
will be considered as having passed inspection for the
event until the finish is made official.
DEFINITION OF STOCK: In the
following Rules you will see the term OEM Stock used. This
means Original Equipment Manufacturer. The parts must come
on a standard production car. Special "Off-Road"
or race parts will not be permitted unless pre-approved.
No carbon fiber or titanium engine or chassis parts unless
approved by track officials.
ILLEGAL ITEMS - Absolutely
NO removal of, alteration of, or covering of casting
numbers, part number_ manufacturers name, logo, insignia,
etc., from any item on the race car. To do so makes a part
illegal a will be treated as such. If you come up with a
rare part that we cannot find listed for passenger car use
the burden of proof is on you! At any time you may be
asked to remove a head, manifold or possibly entire engine
for inspection. Failure to comply will result in the same
penalty as if it were illegal
INSPECTION - All model,
engine or equipment changes or modifications not
specifically addressed in the rulebook must be submitted
