This weekend marks the 10th edition of the Superkarts! USA Pro Tour SpringNationals. The event is set for May 3-5 at the Utah Motorsports Campus as SKUSA returns to the Erda, Utah facility for the second time in series history. Formerly known as Miller Motorsports Park, SKUSA first visited the facility outside Salt Lake City back in July 2012 for the SummerNationals that year. The 9/10-mile Alan Wilson-designed karting circuit is named ‘Star Trek’, which will be contested in the clockwise direction – the opposite of the 2012 visit.

Pro Shifter
The IAME SSE 175cc powerplant made its debut at the SKUSA Pro Tour WinterNationals with two different drivers claiming victory. Andrew Bujdoso mastered the rain on Saturday to claim his first SKUSA Pro Tour victory while defending champion AJ Myers triumphed on Sunday. It was a Croc Promotion sweep of the victories thanks to Bujdoso and Myers, however, the roster has changed for Mad Old Nut Racing operation. Bujdoso remains, entering the SpringNationals as the championship leader by 10 points over Myers, who becomes a former teammate. Myers was released from his spot at MONR and has joined CRG Nordam, making his debut with the team this weekend. Myers brings with him the SKUSA #1 plate, joining SKUSA #2 plate holder Kyle Wick under the CRG Nordam banner, who sits third in the championship chase heading into Utah. Completing the silly season between races, Myers spot at Croc Promotion USA was filled by 2017 SKUSA Pro Tour champion Jake French. The Texan has spent the last month testing and racing with the team, and makes his return to the SKUSA Pro Tour this weekend. Read full story on eKartingNews.com
