Ok, I just got done with a 3 day driver's school at the brand new Thunderbolt Circuit at NJ Motorsports Park in southern NJ. The track has 5 braking zones on a 2.1 mile circuit. 2 of these braking zones include braking from 100+ mph to about 60ish including the turn 1 where I was getting to 135+ and had to brake to 65-70.

The brakes never faded at all the entire weekend. They were just as strong on the last lap as they were when I arrived at the track. Also, I was braking nearly as deep as some of the guys with aftermarket brakes which says a lot considering the weight of the E92. I was using stock pads and stock tires.

Bottom Line: The brakes are very effective on the track, there is truly no need to change them or upgrade to an aftermarket brake system for track use. The only reason to upgrade the brakes, is because they aren't all that nice to look at (calipers not rotors).
