There is no greater feeling then returning back to where it all began. Superkarts! USA is set to take pleasure in welcoming the SKUSA Pro Tour back to the Simraceway Performance Karting Center in Sonoma, California. The 2017 SpringNationals returns back to the same facility where the inaugural SKUSA Pro Tour event took place back in April 2010. It has been a long seven year journey with the organization evolving and the championship series establishing itself as THE pinnacle program in North American karting.

The bar continues to rise, as this year’s SpringNationals is set to be another record-breaking event as the biggest race ever to be held at the Simraceway karting circuit. Over 200 entries have been collected to date at the SKUSA home office for the May 5-7, 2017 event. The track is among the most picturesque locations in North America, located on the side of Sears Point in the Sonoma wine country, roughly an hour north of downtown San Francisco. It is a true destination location. For the racers, the track is tremendous and ranked among the best there is. The ‘Reverse National’ layout provides some of the best racing with plenty of passing opportunities, and the famous ‘Tic-Tac-Toe’ section of the course is sure to test the drivers.
