All my experience has been with cast IRON rotors, porosity is a
manufacturing defect, all too common on off-shored parts. I've never
seen steel rotors, the friction coefficient will be different and they
probably won't last as long. The graphite pockets in the cast iron
help with longevity.

This is the factory rotor in question.

Doesn't mean much. GM, Ford and Chrysler ALL have had problems with the
cast iron rotors used on their vehicles. GMs had slag inclusions and
delamination issues as a result.
Ford had a similar problem with rotor rust causing problems
Chrysler as well had problems.
