Zaring earned his name of "Daring" Bill Zaring and "Wild Bill" due to his aggressive style of racing on the oval track. He began racing in 1938 in Colton, California. He, finished in the money consistently and won the URA Red Circuit title in 1948.[2] Zaring was one of the many drivers who raced for the Edelbrock racing team.
Zaring raced big cars (now known as Indy Cars) from 1948 to 1955, which were big when compared to midget cars. He never achieved the fame racing them as when he did while driving midgets.
