*** what are the best rs6 rotors and pads***

[GmbH1]

I'm going to have to replace the rotors and pads soon on my C5 RS6 and looking for something that's good quality but also not the most expensive. The pads on there now were put on by the previous owner so I'm not sure what kind they are but they always squealing like crazy and super annoying so I'm guessing they are ceramic. The other thing I was wondering is if you always have to replace pads and rotors at the same time or can you just do the pads if the rotors are in good shape still cause I've heard a few different things about this? Any advice is much appreciated.

Thanks
