"If they're built to the same exacting standards
(sic) as the drums they may contribute to the shakes, rattles and
rolls.
Anybody balanced their rotors and, if so, was it worthwhile?"
Since rotors are turned on a lathe already, in their manufacture, rather than
cast, like the drums, and have less overall mass to start with, I would assume
that they are by design better balanced...
Also, if found to be out of balance, what would you do to correct them, since
the calipers wipe the entire outboard surfaces? Try turning them on the lathe
again? Potential gain seems miniscule...
