Opti rotor
Opti rotor Bought a new optispark and got my rotors mixed up. Its a GM opti so they look basically the same and there both dirty since I have handled the rotor with greasy hands. Not sure how to tell them apart? The only difference I see in the rotors is the metal piece one is more black and one is more brown
you mixed up your old one with the new one? is that what you mean? you should be able to tell. my old one looked worn out on the metal part. new one was clean and no evidence of wear or it having electrical current sparking on it
