OEM=original equipment manufacturer The spirit and intent of these rules is to maintain the integrity of stock car racing. In recent years, stock car class rules have moved away from the original intent of maintaining an entry-level or cost-effective class that is easy as possible on the common man s wallet! Help us keep the integrity of the rules by conforming and abiding by the rules in keeping with the intent of safeguarding entry-level and cost-effective racing! Do not read between the lines, if something is not in this rule book, do not assume you can make things up on your own, ask questions clarification if you are unsure of anything. The assigned Technical Inspector has the final say in rules clarification. Although these rules were designed around already existing like car classes in the general area, there are differences, read carefully, I didn t know is not an excuse. Main thing, JUST HAVE FUN. 5
