I've have noticed that the rules have not been enforced as far as safety equipment at some of the tracks I go to they are NHRA and IHRA tracks. I have been resisting putting a roll bar in the car because it then becomes a "race car" .... I guess you can't have your cake and enjoy it too . It is confusing with the newer cars being legal without a roll bar. Maybe that is why tracks are are not as strict as they once were.
