Glad to help.
No, it's the peak temp that causes the rotor cracking. With better ducting, the temp would be lower and the thermal expansion would be less.
Incidentally, when I had my car up on jackstands yesterday, the inboard rotor faces have much less graining/spidering than the outboard faces. Based on that the brake ducts are getting more air to the inboard of the rotor and the outside is relatively hotter. This makes me wonder if we'd see the same asymmetry with the dba rotors with their different vane design.
