Bryan;
One more thing to check-- make sure your lug nuts are evenly torqued to
their specs. Overtightening them will distort a rotor.

Bryan;
If this is happening to new rotors, I'd take them back and complain
about this problem; it should not happen in so few miles.
Good quality rotors should not distort or heat-spot in 800 miles! Make
sure your caliper pistons are not sticking before raising a ruckus with
Raybestos about the rotors, though.

Here is part of what it says:
"Rotors can also develop hard spots that contribute to pedal pulsations
and variations in thickness. Hard spots may be the result of poor
quality castings or from excessive heat that causes changes in the
metallurgy of the rotors. A sticky caliper or dragging brake may make
the rotor run hot and increase the risk of hard spots forming. Hard
spots can often be seen as discolored patches on the face of the rotor.
Resurfacing the rotor is only a temporary fix because the hard spot
usually extends well below the surface and usually returns as a pedal
pulsation within a few thousand miles. That's why most brake experts
replace rotors that have developed hard spots."
