89-91 N/A Rx7 Rotor (N3Y5-11-B10A)
Two required per 13B engine.
It is best to buy these in sets of 2, when we order these from Mazda we are not guaranteed any specific letter weight. Usually they send us a letter C, but that is not always the case.
Be forewarned that purchasing one of these new rotors may not balance to your existing rotor if your rotor letter weight is A or E.
