i have been working on a conversion fitting 944 late discs to bug hubs and am keeping 4 stud bug pattern. you need to fit a spacer between the hub and the inside of the 944 disc depending on your application ~5mm.
i had a bloke i know machine 4/130 into the porsche disc - fits ok and you only end up with 1 hole with a thin land ~5mm. i made press fit spacers to the hubs which align the disc concentrically ensureing no issues.
haven't finished the caliper bracket yet......
using ibiza cupra calipers on mine 54mm pistons.
