No experience with the SA Big Brakes here, but here is one other interesting
note.

The times that big time race teams have the most brake rotor problems is
during testing. Typically a car will go out, run some hot laps, and return
to the pit for a debrief. The car will then go out for a few more laps, and
once again return to the pits. This can be repeated over and over all day.

What the brake discs are seeing is massive heat cycling. The hot laps get
the discs glowing hot in many cases, and then the cars come into the pits
where there is no cooling air running over them as they sit. The cycle is
repeated again and again. So, what the teams see is repeated massive heat
cycling on a large scale with periods of stagnant non-cooling air during pit
stops.

Repeated heavy heat cycling can warp rotors. In real world conditions this
can mean driving over numerous passes, building heat, and then having
insufficient time to cool properly.

I don't know what happed in this case, but I thought ya'll might find this
interesting.
