May 7-8, 2021 Buttonwillow Raceway Park online registration is OPENPeople have been asking about the 100cc classes for 2021 in the CRC. We allow BOTH the ROK VLR & IAME KA. Weights have changed slightly from CoTa earlier in the year. 100cc Junior remains at 310lbs for either engine, 100cc Senior is ROK VLR 350 lbs / IAME KA 360 lbs and 100cc Masters is ROK VLR 380 lbs / IAME KA-390 lbs. CRC will be running all the ROK GP and Shifter classes same as in Challenge of the Americas competition. “We are holding off for another season on running ROK only classes,” explains series promotor Andy Seesemann. “The popularity of the 100cc classes here in California is on the rise for both engine options and honestly has provided some of the best racing all year. Having both the ROK and IAME opens things up for more competitors, which is better for everyone.”
We encourage you to register online now for Round 1 of the 2021 CRC. Pre entry closing date is May 1. There is a $100 late registration fee for all entries posted after May 1 and in person at the event. Racers are asked to bring their own Sunoco Supreme fuel and Motul oil. No fuel or oil will be available for purchase through the California ROK Championship onsite. CRC asks you to purchase these items through your team or favorite kart shop. Practice tires, and transponders can be purchased as extras when registering via MOM.
Each driver who enters the event will receive their driver pass along with one other for a mechanic/helper. Extra pit passes will be available at the event.
Entry fee includes practice Friday and race on Saturday with one set of LeVanto tires for the class entered. We are a no paid pit spot series. Sponsors get priority on a first come, first served basis. Pit with your friends, pit with a team, or pit alone, it still costs you nothing.
