That's why I asked. I was lucky enough to have found replacement rotors from a racer mk4 clio that were slightly used for peanuts! I think they were £150 or something stupid like that, brand new ones cost £550? I was just thinking for the future..
To be fair though they are expensive for a reason. I've used some very aggressive pads through the years and I've properly abused and they lasted much more that a different/cheaper setup would have done.
