Well, my dealer got the new/improved rotors for me and installed them this week per the instructions from Nissan.  They installed new heavier rotors, calipers, etc.. on the front.  I have to admit it feels better than it ever has and is completely smooth braking right now.  The one thing that bothered me though is that they also replaced the rear pads and machined the rotors.  I explained to them that I expect new rotors on the rear since they were already machining them at 12K miles.  The service tech told me that there would be additional instructions from Nissan to complete this fix and it would be taken care of.  Hmmmm....

If this was the first time the rears were turned then I would not be concerned.

It's usually best to make a minimal cut just to remove the existing glaze and transfer layer laid down by the previous pads. The new pads will seat better if this is done. Provided they made a minimal cut you're better off with known "true" rotors than take pot luck on new ones.

To be sure they didn't hog off too much material have them checked - the standard rear rotor thickness is 0.551 and minimum is 0.472 (12~14MM)
