While I don't dispute the quality of Brembo pads, I suspect they aren't low dust. Any of the Ceramic compounds are good for low dust. EBC Red Stuff pads have a good reputation. I have a set, but haven't fitted then yet.
Hawk HPS also have a good low dust reputation.
Slotted, dimpled and/or drilled disks in various combinations - go
Adams Rotors.
If Bendix made a 'Euro' or 'General CT' pad for the S8, I'd recommend those too!
With Pads - the S8 takes the same pad as a Porsche 993T. You may come across a listing for the Porsche which hasn't cross referenced to the S8 (I haven't found any yet!)
