I'm about 40K into my front brakes and starting to get a little whine. I looked at them and they are getting low/worn. Looking through RockAuto I found some Ferodo matched pair rotors. Anyone ever used these over the Centric rotors? I can get two centric rotors for $120 or the Ferodo's for $150. Just wondering if there's anything noteworthy about the Ferodo ones.
