It's likely pad deposits, at least for this car. Maybe ABS related depending on how you brake? You could go get the discs resurfaced, but re-using the same pads will likely have the same results and new blanks are like <$40/ea. A good beating to even out the transfer layer is pretty much your best bet unless you want to replace pads+discs.
Most of us would probably live with it until the pads are gone and replace the discs at the next change.

I try very hard not to get to the point of using ABS - I try to stay just short of that - not saying it hasn't triggered on occasion...
I was and still am skeptical that it's anything to do with warping -- what led me down that path was that for really hard braking they feel very smooth - it's only when you back off on the brake pressure a little that they are uneven/pulse. My thought was that when clamped hard enough the caliper follows the rotor.
My attempts at evening out the transfer layer through 2x attempts have not seemed to cure this... Did 7 stops from ~100 to ~5 at the track bed-in area this weekend - and while they felt smooth during the hard stops, the vibration was back when I went out on track.
Thanks for the thoughts/help...
