Hey again m8
discs aint a problem really just try your local engineering shop (mine were quite happy to do me a set of custom spaced discs(ford 4 stud converted to vaux 4 stud(just tapped holes in between the currents maybe a bit trickier with 5 stud either that or speak to rally design for a set of universal discs your required size they have a BIIIIIIIG range off the shelf and have most stuff (just i'm a cheap git) give them a bell tell em disc diameter and width and spec (ie vented drilled grooved) and get a set of 4 stud m3 discs not too sure about caliper mountings but anythings possible with a bit of thought had RS Turbo calipers on a Nova years ago :)
