The calipers bolt on fine but you either need to use the S14 bolts or have the S12 ones shortened. Then you need to make Two 4mm Pads spacers for either side due to the thinner S12 discs. I used some Ali which were cut and shaped be an exact copy of the back of the Pads. If you do this they will be held in place by the Two pins which hold the pads in place. Then I used some S12 Earls hoses which bolt on but you could use S12 Rubber hoses with some banjo bolts.
