Can you Run 12a Rotors back to front?
 

as the title says...Can you do it?

Currently rebuilding a 12a PP (asymetrical Bathtubs, older style NA rotors, lightened, also lightened crank), and when the rotating assembly came back from the balancer he informed me that since the 12a front rotor was lighter by (11 grams) he balanced it running it in the rear position...

I'm rather hesitant to do so as i've never done this before and despite a lot of research and searching this and other forums cannot seem to find an answer.

Cheers

ignore this...communication failure between builder and balancer.
