You don't want the pads to sweep the edge of the disc, that can cause all sorts of trouble
Inner or outer edge? I've not had such a pronounced area of unused disc before.
Inner or outer edge?
Either. You want the rotor to sweep the entire area of the pad. You could always measure, those rotors might be >160mm over the high points, but if they're clearing the caliper body and pad pins, there's no foul.
