I used to run the 180b strut with a set of Audi 10" ventilated discs and VK commodore calipers this setup only required a 3mm spacer between the caliper and the strut to give the correct pad offset to wear correctly ran this quite effectively for a while still have the discs attached to the 180B hubs no wheel bearings though and the spacers can be some high tensile washers if need be all the disc required was a redrill of its bolt pattern as i think it was 4 x 100 ??? to 4 x 114.3 mm as the disc had the correct offset for the pad caliper etc it fits under 13" rims easy.Stewart Wilkins used to sell this kit many years ago.
