Drivers in the X30 classes are advised to review the updated X30 Supplementary Rules posted on the SKUSA Rulebook page regarding revised technical specifications. Both spark plug and radiator rules are being updated to reflect input from engine builders, tuners and our racers. These changes will take effect in 30 days.

SKUSA National Tech Director

After discussion with a number of engine builders and tuners across the country, Superkarts! USA has decided that VP C12 will be the exclusive spec fuel for all SKUSA classes, starting with races scheduled at least 30 days from today. This change will help stabilize pricing and reduce inventory challenges for our competitors as well as our karting industry partners.

The Pro Tour SpringNationals in Arizona on April 29-May 1 will be the first national SKUSA race to implement this change. As for each SKUSA regional series: the California ProKart Challenge will implement this change starting with the June 3-4 event at Simraceway, the Texas ProKart Challenge will kick it off at their first event on May 20-22 at North Texas Kartway, the Can-Am Karting Challenge will effect the change on their same kick off weekend May 20-22, and the Maui PKC will follow suit two races from now on May 21.

For the SKUSA classes at LAKC, the change will take place starting with their May 15 championship race.

Additional information will be posted on the corresponding websites shortly.
