Tuesday, 08 April 2008 08:57

This coming weekend not only marks the debut of ProKart Challenge North, the new SKUSA program that will run this year at the Infineon Raceway karting facility, it also marks what may be the largest prize purse ever offered for a regional series in kart racing. The Jim Russell Racing Drivers School (JRRDS) has officially announced its commitment to offer an unprecedented prize package totaling more than $50,000 for ProKart Challenge North competitors. The package includes a handsome array of prizes, including introductory courses in their esteemed racing car programs, performance tires, helmets, and more.

“JRRDS’s commitment to our series is amazing,” commented ProKart Challenge and SKUSA CEO Tom Kutscher. “With other series, you’re racing for a jacket. And these guys have stepped up to deliver what could be the biggest prize package ever for a regional series. I wish all of my regions could get this kind of support! This is big -- I can’t thank Jim Russell Racing Drivers School enough for their contributions.”
