    The bore is 57.1 and a typical oem offset of 43-45 - most of us would agree that if you aim for 35 you wont be far wrong.

    Not adaptors but spigots. These make sure the wheel is properly centred which is obviously important. what PCD are the wheels you are looking at? Because i dont know of 5x100 or 5x112 wheels with centre bore of 73.1, this obviously doesnt mean tere isnt any, I just dont know what!!! If the PCD is different to the car then you will need adaptors..........
