IAME Series USA West

The IAME USA West series is organized and promoted by SKUSA, a world-renowned karting promoter and organizer. With a history in karting of more than 25 years and organizing championships spread across the country, such as the Winter Series, the Pro Tour, the California ProKart Challenge and the Texas Sprint Racing Series, SKUSA boasts the most extensive karting competition program in the United States. Such a comprehensive program sets the stage for the annual SKUSA SuperNats, perhaps the most popular karting event in the world, which has been bringing together drivers from all continents for 26 years and brings together more than 500 each year. The SKUSA Winter Series and Pro Tour have been granted official IAME Series USA West status, and Mini, X30 Junior and X30 Senior champions from both series will be eligible to join the IWF representing the United States.
