It was a very hot and challenging day at the Phoenix Kart Racing Association with the first day of racing for the 2018 Superkarts! USA Pro Tour SpringNationals. The temperature at the Glendale, Arizona facility rose to triple digits, reaching 103 degrees before the sun began setting in the west as the podiums were completed. The focus for everyone was staying hydrated and cool as possible. SKUSA offered up a cooling station, extra medical support, and water for all drivers after they got off the track. Prior to the Finals starting, a large dust devil swept the paddock, damaging a number of tents and on-track cameras which forced an hour delay. The day was dominated by a handful of drivers, with five earning sweeps to secure footholds into the championship chase. Read full story on eKartingNews.com

One year ago, Christian Brooks found himself leading the SKUSA Pro Tour X30 Senior championship standings following two runner-up finishes at the WinterNationals. Fast forward to the present, Brooks (CRG Nordam) is in the same position thanks to a runner-up and his first Pro Tour victory at NOLA to once again be the top driver in the title chase. The difference, Brooks is competing at the SpringNationals. His Red Bull GRC schedule did not allow for him to compete in Sonoma last year, while this year he’s gunning for SpringNats victories. Brooks has plenty of success at the PKRA circuit, which puts him as an early favorite. Read full story on eKartingNews.com

Three drivers stood out at the WinterNationals in the S1 Pro Stock Honda division. Austin Garrison (J3 / CompKart) shocked the field after a wild opening few laps to escape with the lead and go on to score his first class victory. The former S2 champion could not find the magic again on Sunday, with former Pro Tour winner AJ Myers sweeping the day toward victory. Myers (TB Kart USA) ran second to Garrison on Sunday, giving the Florida driver the championship lead, ahead of 2017 SKUSA SuperNationals winner Billy Musgrave by 40 points. Musgrave (MRC / Aluminos) stood on the podium both days at NOLA to put him second in the standings, and currently holds the top spot in the EKN Driver Rankings Powered by Bell Racing USA. The four-time California ProKart Challenge champion is the only winner from the last two SKUSA Pro Tour events at PKRA to be in this year’s field. Two others who competed in both PKRA events in 2015 and 2016 were Kolton Griffin (MRC / Aluminos) and Brian Keck (CRG). Read full story on eKartingNews.com

The middle two rounds of the series are set for the PKRA facility, where the organization has visited three times in the previous eight years of the SKUSA Pro Tour (2012, 2015, and 2016).

Musgrave and Drew Tame Streets of Willow During California ProKart Challenge Weekend

The California ProKart Challenge allowed its racers to stretch out their karting machines for the second round of the 2018 season. On March 30-31, the Superkarts! USA flagship regional program visited the Streets of Willow course at the Willow Springs International Raceway facility in Rosamond, California. The 1.6-mile course – with a reduced layout for X30 Junior and Swift drivers – took racers away from the normal karting track and onto a road course, reaching the highest speeds of the season. The 12 categories were put together into four race groups on the day, sticking with the same qualifying, two heats, and main event format. A number of classes were swept on the day, while others went down to the wire.

All six Stock Honda categories took to the Streets of Willow circuit in a combined race group throughout the day, putting 50 karts on track to make every session a busy one. At the front of the field all day was Billy Musgrave. The four-time series champion and SuperNationals 21 victor swept the Mad Old Nut S1 Pro Stock Honda class, but it was not easy. Musgrave cleared the entire race group by half a second with a 1:15.311-lap time, ahead of S1 rookie Rory van der Steur and Josh Lane, making his return to the California PKC. It was Brian Keck that put the pressure on Musgrave in Heat #1, stealing the lead for four laps until Billy retook the position and the win. Heat #2 saw van der Steur leading four laps before Musgrave resumed the spot – right before a red flag and restart cut the session short. Musgrave and van der Steur were able to get away from everyone in the 14-lap Final, making it a duel for the victory. Rory led the majority of the race, with Musgrave leading the final two circuits. At the line, the two were separated by 76 thousandths of a second at roughly 80mph. Lane was on the podium in third to cap off his return to the seat, while Matias Podboj and Peter Abba completed the top-five.
