ProKart Challenge South Heading to Willow Springs
Thursday, 22 May 2008 19:12
As the backbone program for the Superkarts! USA organization, the ProKart Challenge South series will head to Rosamond, CA for round three of the 2008 season, competing at the Willow Springs International Motorsports Park karting facility on May 31. The fast and technical 6/10-mile course is a popular destination for the Southern California competitors, and the PKC drivers are expected to put on an amazing show – especially as PKC has decided that the course will be run BACKWARDS for this event. This could put an interesting spin on things, as the series heads into the season’s third stop with the championship chases now just beginning to take shape.
