ASC Racing provides a venue for late model stock cars similar to those used in NASCAR, Southwest Tour, Grand National, ASA and other series to compete on some of the best road courses in the United States. The series was designed to bring the speed and passion of stock car racing to a level where drivers and teams without large budgets can afford to field competitive cars. The series travels to many of the most prestigious and skilled tracks in the south west, including Miller Motorsports Park, Sonoma Raceway, Laguna Seca and California Speedway.

ASC Racing includes a "spec" class (ASC) which requires that competitors use engines based on a power to weight ratio formula, currently using Hoosier 10" slicks, 6500 RPM maximum limit, no traction control, and other items to keep the field even in terms of car performance and costs.

For those who just want to join ASC Racing with their current stock cars without modifying them to meet the "spec" requirements, ASC Racing also offers the ASC Unlimited Class (ASC-U). ASC-U is open to any stock car from any series that wants to join other stock car racers at any of our events.

ASC is a member run organization; we are open to all member suggestions and are willing to adjust at any time to a majority vote, thus making the group a very tight knit community. With the high performance of the race cars, intense competition, and potential for sponsor support, it is clear why ASC Racing has become one of the premier series in our national road racing calendar.
