I'm hoping this will solve the problem but I have to wonder if there is something else that is out of spec that causes rotors to warp. I've always had problems with this car and have read a lot of posts on this site about shudder. Perhaps calipers? I have two new hubs. Or perhaps when rotating and balancing tires they apply uneven torque?
Calipers won't cause shudder unless they aren't bolted down tightly.
Let us know how those rotors work out, and if those fix your shudder problem.
Have you had your axles inspected? I suspect that mine on my Bonneville are bad as I had all of the other suspension components inspected and I'm still having a vibration at higher speeds.
