I get this condition everytime I go to the track with PFC01 pads. Try to warm your brakes up and avoid slamming up against ABS when they're cold.

+1. Happened to me before.

The trick is to buy a set of aggressive front track pads, install and run them for a few days of street driving. That should clear the rotors of any pad deposit.

No BMW I've ever seen so far has pads adequate for track use - so if you want to trak, you need to always use track pads (and fluid). What can I say, pads may be adequate on Porsches, but you pay a LOT of extra $$$ for that capability.

I've done many track days with BMW's on stock rotors, just with fluid & pads. It's a simple formula, cheap and reliable.

And each time new/different pads go in, proper bedding in is required, not optional.
