What is needed to fit them to a mini?

IIRC a banjo hose to join the two inlets up, a set of metro drive flanges and the correct bolts off a ERA turbo to bolt the caliper to the upright.

I haven't got a clue about them sorry, I just took them from a car that was going to be scrapped with the intention of using them as they'll fit under a 13" rim but I'm just going to go for 15's now.
