I can just picture hundreds of big, burly race car type guys standing 
around squealling like little kids over some newfound toy.  I would've 
stood there watching, too. (Might even have squealled once or twice 
myself 8*)

The brake rotor on the set of Goodyears I have is a fairly thin disk.  
Weighs a couple...three pounds, at most.  Would the material your 
referring to be cost effective compared to a disk of die cut steel 
(assuming BOTH parts get their prices jacked up because they suddently 
become 'aircraft' quality)?  Would it be as durable? (assuming the steel 
stands up well to chips from gravel and such)
