ASA Late Model Series

The ASA Late Model Series is an American stock car racing series. Founded by Ron Varney in 2003 as the "USPRO Cup Series", it was renamed "ASA Late Model Series" when it was purchased by the American Speed Association in 2004. After financial difficulties during the 2004 season, the series was sold back to its founders, but retained the name.

In the fall of 2005, Varney purchased the Southern All-Stars Asphalt Late Model Series to form the ASA Late Models South Series, plus the creation of the ASA Late Models North Series as regional touring series. The ASA Late Model Series was renamed the ASA Late Model Challenge Series.
