The California ProKart Challenge is set to resume its 2017 championship chase, having taken the month of May off for the running of the Superkarts! USA Pro Tour SpringNationals. The SKUSA flagship regional program is adding another circuit as part of their flashback tour, traveling to the CalSpeed Karting Center in Fontana, California on June 2-3. This year, the CalSpeed race will be the third stop of the championship chase, with a number of drivers in solid position after the first two events. The CalSpeed facility has become a major fixture in southern California karting over the last decade, and the 3/4-mile ‘Grande’ layout is the proposed course for the event. This will be the first time the program has visited the circuit – located just outside the Auto Club Speedway – since the 2010 season. A number of current California PKC karters were part of that January 2010 event, which kicked off that season’s schedule.
