I had pretty bad brake pulsation on my BRZ after several track days - I had read that warping was unlikely, it was much more likely uneven pad transfer. I took all the rotors off and sanded the he** out of them with garnet sandpaper such that there was no pad material on the rotors.
Pulsation still present.
Bought a runout gauge and found there was a fair amount of runout - can't remember the #'s, but it was out of spec - so either warped or thickness variation. I replaced the rotors and the pulsation went away, but came back after another 3 weekends. I've added some brake cooling to see if that keeps it from happening again.
