I'm just running Pagid discs and pads on mine, and have no complaints. It's a standard S3 setup.
On my old A3 TDI quattro with 288mm discs, I did run a set of DS2500 pads and they were very impressive and improved the bite and feel over std ones.
I just haven't felt the need to change the S3 setup though, but then again I don't do track days etc.
