A month after resuming the 2018 season, the California ProKart Challenge returns back to action to begin the second half of the year with the fourth event in the six-round championship program. The Santa Maria Kart Track will host the Superkarts! USA flagship regional program on July 6-7. A regular stop for the California PKC program, the 7/10-mile circuit is located near the Pacific Ocean on at the Santa Maria Airport. Championship hunts are in full chase-mode, with the 12 IAME and Honda categories gearing up for another exciting weekend of racing.

No one has been able to stop Billy Musgrave in the Mad Old Nut S1 Pro Stock Honda class at the California ProKart Challenge. The current #1 driver in the eKartingNews.com Stock Honda Driver Rankings Powered by Bell Racing USA has been perfect through the first half of the season. Last year’s Santa Maria event triggered a three race runner-up string for Musgrave, with Matias Podboj scoring the victory a year ago. Podboj is the top challenger in the championship chase at this point. Jake Drew has positioned himself as the driver to beat in the Phil Giebler Racing X30 Senior title chase. Drew leads by 28 points over Joseph Daniele and holds the advantage in the win column, earning a Round Two victory while Daniele has a best finish of runner up at Round One. Canadian Samuel Lupien and 2017 California PKC Junior champion Trey Brown remain in the hunt.

The total number of racers reached the 150 mark, as the series met the halfway point of the championship chase by putting Round Three into the books.

After a small hiatus for national competition, Superkarts! USA’s flagship regional program, the CaliforniaProKart Challenge, returns to action at the Auto Club Speedway in Fontana for Round 3 of the 2018 championship on June 1-2. The popular venue also plays host to the Los Angeles Kart Club (LAKC) and is among a favorite of local competitors, thanks in part to its proximity and wide variety of configurations.
 
While the 2018 championship is only two races in, some early season favorites look poised to make their bid for the regional title. National #2 Billy Musgravecontinues to be the man to beat in the Mad Old Nut / Mad Croc USA Pro S1 category. The MRC factory pilot has not put a wheel wrong since his SuperNationals 21 victory. But Matias Podboj and Brian Keck continue to give chase and will no doubt look to upset the PKC points leader. Musgrave runs well at the paved CalSpeed circuit, so the two will have their work cut out for them.

Superkarts! USA (SKUSA), in conjunction with IAME USA and IAME S.P.A., are excited to announce details of the long awaited release of the SKUSA shifter engine (SSE). The powerplant has been in development for several months with multiple iterations, developments, and improvements along the way. Both IAME and SKUSA couldn’t be more excited for the next evolution of the shifter platform in Superkarts! USA competition.

“It’s no secret, I’m a gearbox guy at heart,” explained SKUSA president Tom Kutscher. “As far back as the days when I drove in SKUSA myself, I’ve always enjoyed the added challenge of shifting gears. That said, finding the appropriate successor to the current engine format was something I took great care to consider and make perfect.”
