🚨ATTENTION THUNDER CARS🚨 Since there is so much uproar due to the adjustment to the Thunder Car rules on the Quadra jet and the weight requirement, we are not going to allow it at all. The rules stand with Rochester carburetor, they were written as such and released last September. We tried to accommodate but it seems it is more of an issue by seeing and hearing all the complaints. If any questions please contact your race director Jason York. – BIG O Speedway management
