Same here, brakes in and out at the beginning/end of each track day. I've managed to get it down to about 10 minutes per side.

 

I've heard much on the HPS but not so much about the HP+ besides my brother who has'em. Auto-x differs considerably from circuit-x considering the speed difference.

Breaking in new rotors... 3 stops @ 30-0 and 3-5 stops @ 60-0. Is this correct? This is from what I've read. I've changed rotors and such before but not for racing mainly for street use. I've read that even Brembos can warp after track use if not broken in properly.

 

Not sure about rotor break in (or why it would be different), but here is what Hawk recommends for HP+

Burnishing Instructions

1. After installing new brake pads, make 6 to 10 stops from approximately 30-35 mph applying moderate pressure.
2. Make an additional 2 to 3 hard stops from approximately 40 to 45 mph.
3. DO NOT DRAG BRAKES!
4. Allow 15 minutes for brake system to cool down.
5. After step 4 your new pads are ready for use.
