Is Cryo Treatment Worth It for Rear Rotors?

Heading into my first track season I'm pretty much set on buying a set of blank rear rotors since I've heard that the E46 ZCP drilled rotors aren't great for track duty.

Tirerack has plain blanks for $58 each and cryo treated blanks for $82. Is there any real benefit for track applications to the cryo treated rotors?
