You could go for a ceramic compound; EBC "Redstuff" is the first one that comes to mind (mainly because someone else on here has recently fitted them).
How hard to you drive? That's ultimately the deciding factor in which pads to buy.
Using EBC's line-up again; "Bluestuff" is really only for track work (excellent fade resistance, but you have to get them up to temperature before they start working properly), whereas "Yellowstuff" is meant for "fast road and track". I'm not entirely sure where "Green" and "Red" fit in.
