Granted BBKs will perform better than OEM, but as stated in other threads, the OEM discs can take plenty of abuse with the right pads. Also, discs don't have a problem with getting too hot, unless it's to a temperature where they start becoming soft (which is very high!), but discs can get too hot for the pads and the rest of the brake system to work properly.
I've done about 26k miles and 5 track days (search mlhj83 on youtube) with my current OEM discs, and they are still going strong.
