That's pretty cool...all sports cars should be tested like that.
But, if they're so staunch on durability at the track, then why are they using cross-drilled rotors? It's pretty common knowledge that cross-drilled rotors crack more easily than slotted or regular rotors.

A lot of aftermarket rotors have the holes drilled into the rotor after the rotor has been made and these are very susceptible to cracking.
Porsche also uses cross drilled rotors.

As for Porsche--the most abrasive thing that happens to 95% of 'em is on Sunday when they get polished with a diaper.

It's well documented that rotors with cast holes still crack. Maybe slightly slower than true drilled rotors (do those even exist anymore), but still more quickly than plain rotors.

Slots aren't as sexy, but they do seem to take a lot more abuse.
