2015 Factory Stock Rules
(No Changes, Same as Last Year)



The rules are intended to ensure that sanctioned events are conducted in a manner that is fair as possible for all competitors and consistent with the prompt finality in competition results. On occasion, circumstances will be presented that are either unforeseen or are otherwise extraordinary, in which strict application of the rules may not achieve this goal. In such rare circumstances, officials, as a practical matter, may make a determination regarding the conduct of the race, the eligibility of a competitor, or similar matters that is not contemplated by or is inconsistent with the rules, in order to achieve this goal.
