ProKart Challenge South Readies for Return to CalSpeed
Sunday, 22 June 2008 20:44
The ProKart Challenge South, the foundation of the Superkarts! USA regional program, has reached the halfway mark of its 2008 season and will be heading to round four at the CalSpeed Karting facility in Fontana, CA on June 28, running the 3/4-mile Nuovo circuit in the clockwise direction. On tap for the weekend is the normal event schedule for the PKC competitors, which will include plenty of track time, both during the practice and race days, and a fun racing environment where drivers will compete against some of the best pilots on the West Coast. Many of those drivers will continue to rack up points toward the series championships, and a mid-season event such as this can be the start of a push towards the overall title. The series points program offers one drop when calculating the championship, so a drivers’ best five results will count. As such, the door remains open for anyone to grab hold of the class leads.
ProKart Challenge North to Run Sonoma Circuit Backwards
Monday, 09 June 2008 19:23
Superkarts! USA has a long history of new and innovative events over the more than 10-year history of the karting organization. Under a new era for the past few years, this philosophy has remained as the SKUSA staff will be the first program in the Jim Russell Karting Center at Infineon Raceway history to run the national track configuration in the reverse direction, which it will for the upcoming third round of the ProKart Challenge North on June 13-14.

“With the series set to run all year long at the Infineon circuit, we needed to find a way to shake things up for the competitors,” stated SKUSA President Tom Kutscher. “With this new regional program, we need to keep the excitement building as we have done in the first two rounds, and what better way than to make history at this popular track.”

Halen Returns and Utah ‘Brings It’ to Steal Victories at ProKart Challenge South
Wednesday, 04 June 2008 08:41
The Superkarts! USA ProKart Challenge South program reached the halfway point of its season following the third round, which was held at the Willow Springs International Motorsports Park in Rosamond, CA this past weekend (May 31). Running the fast and technical 6/10-mile course in the reverse direction, the PKC drivers enjoyed a competitive weekend as the championship chases became more defined – and took some surprising turns.

S3 Light championship leader Bobby Legate has been near-perfect on the year. However, the introduction of a few new talented pilots this past weekend broke up his winning streak. This list of ‘party-crashers’ included veteran shifter drivers Nick Halen, Mike Beeny and Bonnier Moulton. The trio has been on-and-off participants of the ProKart Challenge over the years, and all three made their 2008 debuts this past weekend at Willow. Halen, a former PKC champion in the S3 class, was on form as soon as racing began, taking both heat race wins and the 20-lap feature. Beeny was second in the main event, as top qualifier Clinton Schoombee edged Moulton at the line for this final step on the podium. Legate settled for fifth after running fourth for most of the race. He still leads in the points standings after round three.  For his win, Nick Halen picked up the valuable Makita Combo Kit (18 volt Impact and Drill) – the perfect tool to keep the father/son team in front of the field. PKC thanks Makita and FX Racing for their support and sponsorship.
