The ARCA Menards Series West, formerly the NASCAR K&N Pro Series West, NASCAR AutoZone West Series, NASCAR Winston West Series and NASCAR Camping World West Series, is a regional stock car racing series owned and operated by the Automobile Racing Club of America (ARCA) and the National Association for Stock Car Auto Racing (NASCAR). The series was first formed in 1954 as a proving ground for drivers from the western United States who could not travel to race in the more traditional stock car racing regions like North Carolina and the rest of the southern United States.
