front rotors issue see inside

What do you make of this? You can barely feel it but its there, like pitting or something, only 7500 miles I like to give it the beans sometimes but never on a road course.

Casting defect in the metal. Surprised it hasn't cracked even though you don't track it. I'd try to get that replaced under warranty if I was you.

Could also be pitted from rust under the pads if put away wet. I made mistake of washing and garaging and two weeks later I left a 3’ skid mark getting out of garage before wheel broke free. Mine has slight pits where pads were, but not that bad.

Washed the car a few days ago, used it everyday since. The way I drive it, the rotor should be clean in 10 min of the first trip, LOL

Did you try hitting it with a sanding block and some 400grit paper?

That's 100% a warranty issue, not normal "wear and tear."

That's not caused by surface rust. You can see the metal is porous, from air remaining during the casting process.
