I´ve had really good luck with the NAPA rotors, although I´ve had to
replace them
twice in a row now, since I was putting the NAPA Lifetime Warranty pads on
wrong
and they wore out too quickly on one side.
Anyway, I have a MoPar rotor on one side that must have 100k miles on it,
and the
NAPA rotor on the other. I used a surface hone to even up the surfaces, but
it´s
not worth turning them (NAPA rotor was $60, or 2/3 the labor of turning).
I think one of the keys to avoiding warpage is how you tighten the lugs. I
use a
good impact wrench with adjustable torque, but I tighten in a cross-pattern,
like you´re supposed to tighten head bolts.
Even doing this, the rotors on the truck from the factory warped.
