The pads sell at Pelican Parts:

About part numbers: for the rears there's only one type
For the fronts I bough the ones which are currently on sale, model # CC-7643-D776
I will report about the dust the produce when I've driven them enough to make a sound report it
Oh btw: Thanks for crossing fingers for my team: We crushed England 4:1
