Zero late fees to register at the track for OK-N

OK-N Class Debuts in Tucson for COTA 2023

Our 2023 Challenge of the Americas Tucson event will be the very first OK-N race in history, and we realize we will have to adapt and make a few concessions. We understand that some potential racers are still procuring engines to be able to race. Therefore, we are suspending the late fee for OK-N entries. If you are waiting for an engine and will be a last-minute entry, it is OK. We recognize that supply is growing and sometimes lagging. So, you may enter at the event with no penalty. Yes, zero $250 late fee for all OK-N entries who register at the event in Tucson.

In addition, we understand that the OK-N class will grow exponentially over the course of the Challenge of the Americas, with more drivers entering as the series progresses. Therefore, this first weekend will be treated as a stand-alone event, outside of any championship per se. Should the engine situation become more stable, we will start a “championship” in Phoenix.

Tucson, Phoenix and Sonoma confirmed as the locations for 16th season of west coast international winter series

NAMPA, ID (September 21, 2022) – The locations have been confirmed for the upcoming 16th season for Challenge of the Americas program, beginning in February 2023.

California ROK Championship Focuses on Pat’s Acres Racing Complex

ROK Vegas prizes and more in special ‘winner-take-all’ weekend in Canby, Oregon

The California ROK Championship has already adjusted for the 2022 season and is continuing to modify moving forward. The Pat’s Acres Racing Complex event scheduled for June 24-26 will feature an updated format to the weekend’s activities. Racing at the historic Canby, Oregon facility is changing from a two-round structure to a ‘winner-take-all’ one-off event. On the line will be prizes for the ROK Vegas event scheduled for later this November.

“We are preparing for an event like no other in 2022 with our weekend at the Pat’s Acres Racing Complex,” stated California ROK Championship promoter Andy Seesemann. “Circumstances and the way the sport is evolving led to what I’m anticipating will be one of the most exciting weekends on the west coast for ROKKERS. The top-three finishers in all categories are receiving prizes to the ROK Vegas event this November. The three-days of action will lead up to the main events to close out the weekend and decide who goes home with the victories and awards.”

The Pat’s Acres Racing Complex facility dates to the 1930’s of hosting events before becoming a kart track in 1965, built by Harry Hegar. The facility was purchased by the Egger family in 1998 and remains a family-owned facility for both karting and other activities. PARC has hosted many national and regional events during its time with the 7/10-mile course providing a significant challenge to drivers in all categories.

With the changes to the Pat’s Acres Racing Complex, it comes with the recent cancellation of the Sonoma Raceway event originally scheduled for August 26-28.

“When we set out with the schedule for the three events of the California ROK Championship, we believed there was going to be enough spacing and time off for competitors to follow the full schedule,” added Seesemann. “Unfortunately, we were forced to drop the CalSpeed weekend and now with events being added in and around our Sonoma weekend, we’ve elected to remove that event from the program. This gives us our one-off, winner-take-all weekend at Pat’s in just three weeks.”

The format will include official practice, qualifying, heat races and a main event to close out the California ROK Championship event at Pat’s Acres Racing Complex for all classes. Prizes for the top-three finishers include;

1st place: ROK Vegas ticket (includes entry, race tires, fuel)
2nd place: ROK Vegas entry (entry only, no tires or fuel)
3rd place: ROK Vegas race tires (no entry or fuel)

Pre-registration is open for the California ROK Championship event at PARC at The fee includes entry for Friday practice along with the racing over Saturday and Sunday, two sets of tires, fuel and oil along with pit pass for mechanic and driver (one set only for Mini ROK and Micro ROK).
