What??? Grooves on rotors indicates a problem! Could be a small rock lodged in there but most likely they assembled the parts wrong, Get it Checked!

You honestly think a rock could withstand the force of the calipers squeezing together?

Rotors get f'd up in all sorts of ways that are totally normal. They are like quantum entities, they get messed up looking just by observing them.
