Street car or not,The rules ARE the rules.It really comes down to the tech guys that check our cars before we can race.I admit I have not always been able to pass tech,but they never checked.The tech guys will take you on your WORD when they ask,do you have a trans sheild,nuetral saftey swith,ANTIFREEZE ETC.Most of the time they just look at the tags on the belts & helmut.Some of the rules are stupid,but we still have to abide or try to get them changed and I refer more to certain certifications.
