you really need a rule book,no roll bar needed 11.50 et...roll bar to 10.00 if the fire wall and floor is stock. roll cage if the floor or fire wall has been modified.there is tube size and thickness rules...9.99 down,needs to be certified.aftermarket axles and no c-clips past 10.99 and on and on and on. sfi safety parts all over the engine and trans..wheel stud lengths,helmet and driving suit specs..i could type all night ..you need rule books.
