Could the wheel surface be out of wack and warping the rotors?

I suggest removing the wheels and cleaning the mating surface between wheel and rotor - ideally, you should also remove the rotor and clean the rotor/hub interface, but let's assume this was done when the rotors were changed.
VERY IMPORTANT: Make sure the lug nuts are tightened gradually with a torque wrench. 95-100Nm should be plenty. Uneven and over tightened lug nuts can easily produce brake vibes.

I just had the front rotors replaced at 21000. When the brakes heat up and you reduce speed from 50+ you can feel a noticable shimmy. Am I missing somthing else?
did you bed in the new brakes when you got them?
or did you just start driving?
does the shimmy only occur under braking?

Balenced every 7500 miles
OE pads & rotors
A poor Mating surface sounds promising combined with any amount of torque could warp the rotor. I'll go out and check their work with my torque wrench. I did ask them to double check the spec and hand tighten. Who knows.
Warrenty - Yes its documented to this point. I just couldn't believe the new rotors didn't fix the problem.
I just started driving but I did try to go easy for the 1st 200 miles. Yes it only occurs while braking.
