problems with ATE Power Discs?

> It turns out my less-than-a-month old Power Discs were warped.

A frequent cause of warped rotors, fro what I have heard, is improper 
lug nut/bolt torquing.

Been running power discs for years with no problems, in fact, it seems, 
less warpage issues than I ever encountered before using them.  But 
that's just a data point, not a blanket recommendation.
