I know there is a nice brake upgrade available for the 2wd Cosworth, using Focus RS discs together with 4 pot Brembo calipers from a BMW e38 735i.

Unfortunately you cannot use those discs on the 4x4 as the disc offset is too much. So I thought it might be possible to use the e38 calipers with some Hispec or AP discs that fit the 4x4. But it turned out the calipers are also too wide (again due to the disc offset) and will touch the spokes of the wheels.

Does anyone know if there are other OEM calipers that will fit on the 4x4? It seems like all 4 pot calipers are too thick and will have the same problem. Of course you can get some AP or Hispec 4 (or 6) pot calipers that will fit, but I think it will be a lot cheaper to use calipers from a different car. I was also looking at some Porsche Cayenne 6 pot calipers, but cannot find what size it is.
