I feel like it could be the biggest class around here if more tracks would get on board and create a similar set of rules. There are 3 tracks in the area that have a sportsman type class but the rules are structured so differently that a car can not go from one track to another to race. I think that plus extremely low pay keeps several other cars from running in the class. Matt49 I think 604 crates could run in this class without any issue. Certain aspects of this rule set could be modified to allow more people the opportunity to race what they have without too much of a negative affect.
