IMO, .012" is too much, even if you don't feel it in the pedal. Of course,
it might be the hubs rather than the rotors ...

Absolutely; especially if you don't see a corresponding variation in
thickness. After you check the mounting points, you can try turning the
rotor 180 relative to the hub and see if that improves things.
