content: This was a perfect replacement for my factory rotors. The anti-rust coating seems like it will last for a while, but I still used anti-seize when putting them on to make sure they are easy to remove later. These rotors cost me less than the brake shop wanted to charge to remove and turn my original rotors.I've only had the car out for a short test drive, so the pads aren't fully bedded in. They seem to be working well, with no judder.I held onto my factory rotors just in case (I think they are thick enough to turn them one more time and reuse them), but I don't think I'll need them.
