Since last June we have only been running IROC style using either track owner supplied or club owned cars. This week we will be doing one race using our own cars. The format will be novel in that a driver can pick a car from any of our regular classes, so it is likely that cars from different classes will be on the track at the same time. If I understand it correctly the results for each car will be compared to the record for that class so each driver will be racing against the record and not necessarily directly against the other drivers. A person that set a new record for the class that he was in could beat a car that was slower than the record for a different class even though he did not get as many total laps.
