[s-cars] Silly question - cryo treated rotors

[Hayes Myers]

Yep. It's all about working the metal..whether through temperature or
through pressure etc.  Learned a lot about this in undergrad (Engineering)
and it made no sense...until I read a bunch on building motors.. ie: why you
would work harden a connecting rod and how it works.  Fascinating stuff
..makes me think that metal is 'alive' really.

Cheers

Treating metal via cryogenics is supposed to align the molecules.
Aligning the molecule improve heat dissipation. I'm not a metallurgist,
but seems to make sense for very high heat scenario's - I don't think
its worthwhile for daily drivers - except for beer conversations :)

Hi Y'all,

I frequently see ads for cryogenically treated rotors at, of course, 
premium prices.  Laying all the bullcrap aside is there actually any 
added value for this treatment or is it just marketing hype?  IOW, is 
it worth the added expense in terms of better performance or longer life
or...?

Bob
