Well, "on road fuel" would indicate that all on road fuel classes are at one event since there isn't any listing for a separate on road fuel class..
(sorry, sarcasm today... !!)
Yes, the on road fuel nats at MRO is combined with 8th and 10th fuel on road classes. The limit will be 20 qualifying heats which is equally split between the two classes. Registration for the event will open 90 days prior to the first day of racing AND the top 20 of each class will have a seven day early grace to register by contacting the Administrator with payment in full and ensuring current membership.
