you should have 100mm flanges on that, but best to check to be 100% sure

just need the outer cv joint and flange from 5 stud mk3 or corrado, then press em into 256mm+ 4 stud bearing carriers. you'll need a new wheel bearing too as removing the old flange will destroy it.
then once you have done that, you need to redrill the discs to 5 stud, or fit 280mm brakes and buy early Passat B3 VR6 discs. unfortunately these are VW only:
