from China and it sucks. We've put more miles on our Odyssey (same year). The OEM rotors were crap and warped pretty quick. The replacement rotors were NAPA brand and they went for 70K miles without a single issue. Still just as smooth at the end as they were at the start.
Can't remember who was making the NAPA rotors back then, but they went Chinese and they're now crap. Can't remember which rotors I got last time, but they only went 30K before warping. I don't know who's rotors to use now. I'm trying Bosch, but who knows anymore. They're all living on names that no longer mean anything since they all get their steel from China.
I'd pay extra if there was a company out there that could promise me they were using good quality steel.
