and that could be caused by many other things and AFAIK most of the time the heat is the main cause of the cracks and busted rotors
I agree with you about the fluctuations but the keyword here is "
huge fluctuations" and like I said I don't think the fog light brake ducting can cause those fluctuations and do any harm than the good.. I also understand that certain pads require certain operating temps you really have to heat them up but that's still a different thing
maybe @
rice_classic can chime in and share his experiences on the subject (
overcooling the brakes)since he is an instructor here in PNW and attends many races
