can you guys help settle an issue, i don't have a rule book. are iron rotors illegal in most classes and, if so, why? what classes are they legal in? tia
duh...found the rulebook. superstock-no iron, superbike-whatever. this still leaves the question-why? i've heard iron cracks. is this the reason? let the superbike guys risk catastrophy? some mfgs claim to have solved this problem. so...do the rules need updated? what am i missing? ???
Cast iron rotors are not allowed but ductile iron rotors are. So Brembo superbike, Brake-Tech, PFM, and any other ductile iron rotors are OK for supersport classes.
What Phillip said - as to why - cast cracks (usually in a spectacularly bad manner - ask Dave Sadowski), ductile doesn't.
No the EBC rotors are not cast. You should always check them for craks or other problems of course but the odds of them failing in the same manner as cast ones is almost nil.
thanks all. so, i can assume that when the rules state 'no iron rotors', they're not including 'ductile iron'? another question, if i may. i have 'beringer' rotors but am unsure of the appropriate pad. what are the readily available choices?
