Are you replacing rotors only or the hats too?
If rotors only, then just pay attention to the order in which the nuts and mounting hardware come off the old rotor and replace in reverse order. I think the hat has a chamfer on one side of the outer edge that has to be positioned correctly in order to allow the rotor to float when torqued down, otherwise the hat could be installed backwards to the rotor.
I am not 100% sure on this as its been a few years since I replaced mine and I put everything back together in reverse of how it came off.....using the assumption that the previous mechanic knew what he was doing and had assembled it right before I got there.
Those are small 4mm nuts I think so torque to snug using a 1/4 inch socket and don't overtighten them. I think they use lock washers to prevent losening.
