All cars must be stock in every way except as modifications allowed by these rules in the interest of  safety. The word “STOCK” means as it came from the factory for the particular make, model and year for a car. In some respects, this philosophy is a throwback to NASCAR stockcar racing as it started in 1949. Any reference to NASCAR LMSC rule or section within these rules refers to the 20052004 NASCAR Rule Book. These rules are subject to amendment at any time when notice has been given.
