Hi folks just a few questions. I know the Boxter calipers fit on the 312mm upgrade discs and the Boxter s and 996 carrera calipers fit on the S4 disks. But which ones fit on the 322x32mmdiscs? The 996 turbo or the GT3 4 pots? What size discs do the cayenne turbo 6 pot calipers need? Can they be used with a smaller disc than say 345mm? I ideally would like to still be able to run my 17s even if spacers are needed.
