I think you might have been braking more than necessary. At those ambient temps on all seasons, you shouldn't have heat soaked them.
N20 is all about the fuel efficiency right?

I believe the 328 xdrive has ~12" front rotors and is ~3700lbs. Not exactly a ton of heat capacity for such a porky car.... I am sure there was room to improve my driving but on the other hand, I drove the 997.2 in a similar fashion and it did not have the brake issues. (is it really that surprising that the brakes on a base model 328 need to be upgraded for track use?)

One thing that might have worsened the situation is that the traction control was left on for most of day. The brakes seemed to last longer when I drove in DSC OFF

EDIT: my griping about the brakes aside, I want to reiterate the fact the car was a TON of fun. Non track users aren't going to notice any of these things we are talking about and track users will know better than to spend their money on this particular configuration....
