Need A Rotor Diagnosis (pic inside)

[KAA]

Those spots are gone. They disappeared the day I went to the drag strip. I also did an open track day since then and they did not reappear. Odd.

The pads came with the late model F-body kit I installed. They're the Polymatrix E compound pads. They seem to work great. The rotors don't show any signs of wear but I do think they're getting warped. The only time I notice it is on the track when I really hammer on them. When I get down around 60-50 mph the front end starts to shake. I never feel any pulsation in the pedal and the steering wheel doesn't so much as twitch. This started after about 10 laps the first time I put the car on the track. They don't fade but that shaking is definitely getting annoying. I'll be trying a different rotor. Most likely a slotted non-drilled rotor from Coleman racing that I can bolt directly to my Coleman aluminum hubs and eliminate the Wilwood rotor hats.

The warp you will feel in the pedal. I would recheck wheel balance. Could have thrown a weight.
