Can get 8, 10 or 12 for the front sets,
or 4 or 6 for the rears.
Plenty of people have said that they work really well,
the 8 pot G4/D2/Attkd calipers take an AP 6 pot pad.
I was looking at the 330mm 8 pot ones for my car, but decided that 2k for a setup that isnt much bigger than the 33 gtst standard setup isnt worth it, if I change to 18" wheels I would grab the 356mm kit in a heartbeat.
