[s-cars] Silly question - cryo treated rotors

Yeah, I've heard all that stuff and it makes little sense to this 
chemist.  Molecular motion (required if the structures are to 
realign) slows down at lower temperatures.  The argument would favor 
heat treating not "cold treating".  But what do i know?  I guess 
that's why I first posed the question
