Hey anyone had these rotors for more then a year on the xf what the quality and how are they holding up. I have to do this soon as I have bad squeeeeeeeeeellll and they dont appear to have ever been changed in the 65k thats on my car. Thanks for the input and help guys! I would actually like to make the dragon this spring its actually not that far from me in va and some nice and shiney breaks would do me just right!
