The United States Auto Club's CRA (USAC/CRA) Sprint Cars made their debut on March 6, 2004, at Perris Auto Speedway.
Using non-winged, 410 cubic-inch powerplants, the series showcases some of America's most traditional sprint car classics in the Southwest.
Many of the stars in the series have campaigned on the West Coast for years. They include five-time champion Mike Spencer, Rip Williams, Cory Kruseman, Damion Gardner, Nic Faas and many more.
With engines producing upwards of 800 horsepower, these 1,200-pound rocketships combine the thrill of raw power with the heart-stopping action of non-wing sprint car racing. Dirt rooster tails, wheel stands and three-wide racing are the norm when these bad boys come to town.
Sprint cars also run on paved tracks, and any driver with aspirations of a championship must be able to negotiate both dirt and pavement.
There are a few sanctioning bodies for non-winged sprint cars.
USAC has become the premier series for non-winged sprint car racing throughout the U.S., especially after taking over the Sprint Car Racing Association (SCRA) and turning it into the Amsoil USAC/CRA Sprint Car Series.
This series has become the premier non-winged sprint car series on the west coast of the U.S.
USAC also has hosted the Silver Crown series based in Indiana for decades. The Silver Crown series was started in 1972 as an offshoot of the series that competed for the National Championship Trail including the Indianapolis 500, known as “big cars.”
