Rotors are loose
With the wheels off, there is movement of the rotor indepent of the lugs bolts.
Seems like there should be a spacer around the lug bolts to keep the rotors from moving.
The rotors are brand new from Napa. With the stock rotors, one had movement and one was fine.
What am I missing here?

Hummm.... Your lugs are pressed into the wheel hub flange. The rotor and the wheel slide over the lugs and both are held in place with the lug nuts. This is part of why torque the lug nut to the proper torque specs... and pattern is so important.
Proper lug nut torque'g will ensure all of the parts are properly centered.
Of course the rotor is limited in it's movement by the brake caliper bracket.... am I missing some thing? Was that your question?

I wonder if your brake pads need replacing??
When I put on the new NAPA rotors there is some play in the rotor until I bleed the brakes and put on the wheels. Then there is no play
But if the wheel is off there will be some play
Remeber to torque those lugs to 100 lbs.

The rotors are free floating. The only thing that holds them down tightly is the wheel (when it's torqued down). The brake pads should hold it pretty decently but that is not their function - more of a side effect than anything.
Long story short, it's normal.

Thanks for the help.
I actually did replace the pads when I replaced the rotors.
The movement is too much. When I stop you can hear a popping sound from the rotors rotating and hitting the lug bolts.
I torque the bolts down to 100 lbs. And I do it uniformly. I torque everyother bolt till they are all done, then I drive the car around the block and recheck. I also torque the wheel lock nut.
I checked my friends car recently when his wheels were off and there was no movement with his rotors on the car. There was also a metal "washer" that was around 2 of the lug bolts.

In other posts about this problem, symtoms like those you describe have turned out to be due to failure to clean the hub surfaces thoroughly when replacing the OEM rotors. Might check that if you haven't already...good luck.

Regardless, this popping sound you're hearing is not the rotor. Think about it. You have a wheel, torqued in 5 places down to 100ft/lbs (which is a lot), sandwiching the rotor to the hub. Do you really think it's moving? It's not.
Reach through your wheel spokes and try to move the rotor. Not a chance - right?

Aftermarket wheels, however, do not have this counterbore, and it is very necessary to remove the clips when bolting on custom wheels.
