Don't worry if you receive rotors with scuffs on the zinc-coated surface - your first few stops after installation will remove the coating entirely from the braking surface. During transit, it's possible for the coating to get scratched or scuffed.
Unfortunately, we cannot completely prevent this from happening, and the rotors superficial and purely cosmetic scuffs typically don't need to be replaced. Rest assured, these scuffs don't affect the performance or protection of the rotors.
