Rotor Designations And What They Mean....
#1
We know MAZDA designates a series of rotrs by Alpha designations, but what EXACTLY does it mean? When you order a new rotor from MAZDA you are not asked for a Alpha designator within that series (TII,NA and year model).
So what differentiates the various rotors?

the mazda parts system says, any new rotor for a given application will work in that application. for the 79+ cars there is only 1 part number for a rotor for a given engine "series", except the 12a and renisis which have front and rear rotors that are different. so for example for a non turbo 89-91 rx7 there is one part number for the engine rotors, and it will work in any 89-91 non turbo engine.
to find a factory reference to the letter designations you have to go back to the pre rx7 stuff.

"A" being the heaviest, and "E" being the lightest.
So, on average, "A" versus "E" would be 8 grams.

Difference between the S5 NA B and D rotors I had was 46 grams
