I'm upgrading the rears on my Mk3 to the Mk4 rear calipers, and I've got pretty much everything figured out. Then I stumble across a deal from a local parts supplier, $70 for Mk4 rear rotors/pads. Will the Mk4 rotors/pads work?
Also, it is possible to replace the rotors without redoing the wheel bearings? They were done in the last year or two and it seems like a pain in the ass to do them. Or is this a "save yourself the headache now and just do it" situation?
