Ben i prefer your one more OEM.. can you not fit without the boss as i dont like boss's and they push the wheel forward dont they ??
Its the same depth as the Audi wheel on its original boss (but I'm not sure how it compares to a std MK2 wheel).
The original Audi boss has a larger spline - so it doesn't my version of the Golf - again, not sure how it compares to the larger spline '90 spec. The OEM wheel can be removed from its OEM boss and the 6 bolts are in the same place as my Momo boss (win!).
