In the 1920s and 30s, Daytona Beach became known as the place to set world land speed records, supplanting France and Belgium as the preferred location for land speed records, with 8 consecutive world records set between 1927 and 1935.

The cars continued to improve, and by the late 1940s, races featuring these cars were being run for pride and profit. These races were popular entertainment in the rural Southern United States, and they are most closely associated with the Wilkes County region of North Carolina. Most races in those days were of modified cars. Street vehicles were lightened and reinforce
