Might not be much help this, but I had the same issue on the old mk4. Fronts were no issue, but at the back the bit the spacers centred on protruded about 5-8mm too far. I tackled it by removing the little hub cap and taking it down about 10mm with the angle grinder. Hardly a great solution, I couldn't refit the caps, but the alloys had snug centre caps of their own and ultimately I wouldn't be getting debris finding its way in. It worked.
