Gambba, (SPELLING PLEASE!!! /ubbthreads/images/graemlins/grin.gif)
I dont know if its just me but my greenstuff pads produce much more brake dust than my stock pads. I find myself having to clean my wheels much more often. I had read previously about the greenstuff pads producing less brake dust, but I can safey say from my experience thats a load of rubbish.
I am definately thinking of trying other pads when I get over to changing them, but still not sure what to get though.

This tells me that you are a hard driver (well of course you are you live in the land of the rally track) and that's when the greenstuffs really show that they aren't good for hard use, the amount of dust is because the compound is relatively soft and wears quickly when at the higher operating temps. When we talk about keeping the wheels clean all that we are actually referring to is the fact that the compound of the greenstuffs contains no metallic elements such as other pads, and these metallic particles are what make cleaning wheels such a pig most of the time, as they are extremely hot when departing from the pad and have a tendency to embed themselves in your nice alloy.
If you are making lots of dust with the greenstuffs, way above what you had with the standards then I would recommend replacing them before you possibly kill the discs, with either some ceramic pads such as the Redstuffs (As I have found these to be good, and would be very suitable for cars heavier than the A3 IMO), or some performance pads from the likes of Ferrodo, ATE, AP, etc...
