I fitted Brembo pads to the front, the old discs (brand unknown) were ok, on the back I fitted febi-bilstein discs & blueprint pads, after 2 & a half years they are all fine, hard to tell with the backs but there was an improvement when I fitted them, the Brembos on the front are definitely much better than whatever was on it and have still have strong positive stopping power. I bought them on Amazon when they were cheap.
I've also had good results in the past on other cars with Borg & Beck discs & pads.
