What about the 6 pots from a Ghibli? I'm half tempted to pinch the ones on my Brother's car for a trial fit...
Didn't know how the standard callipers are mounted so thanks for the clarification. I was thinking of using the larger Ghibli discs though.
From what I can recall of changing the discs and pads on my brothers car last summer, I think the radial mounts are like the 330's on a gta, they have a bracket that effectively makes them lug mounted.
I had AP 6 pots on my gransport which fitted behind the larger gransport wheel with a cigarette paper to spare. @BennyD owns them now so perhaps he can help with some measurements of what is the maximum fit?
