I have a rotor that have a 'C' on the gear side and a 'E' on the other. I was wondering if one side ment the weight in order to attempt to match it up?



Thanks

Well, my B and D rotors had a difference in weight of 46 gms. Still within the mazda spec, but you would not have beleived it to see them jumping on the balance stand

take a look at this: Engine Building Tip from the other board.
