+1, flushed with better fluid (gold stuff) and changed to pagid rs19s. we had a rainy weekend at VIR, so they didn't get as hot as normal, but performed much better than prior 2 weekends using stock pads.
If you're running stock pads, try to take a 5-10 minute cool down lap around the padock when you come off the track, the pads / rotors cool enough so they don't get the bad vibs next time out. Three of us with '08 M3s experimented with various pre/post session rituals, and that was the best. After a week of normal driving, the rough stuff goes away and brakes are back to normal.
