Metalurgy plays a roll as well. If you're buying cheapos who knows what they threw into the mix. Just as important as cryotreating in these large rotors is stress relieving after the casting, i.e. keeping the rotor at a high temperature after the cast and then a gradual cool down.

I checked the autozone website, they want $200 for the front axle and list the rotor weight at 14lbs (typo I'm sure).
