Just wondering if people have registered their cars with wheel spacers. I have done a bit of research and apparently spacers that bolt to the hub which the wheel bolts onto separately can be defined as "adaptors" which makes them legal. I do know that spacers that are just circular plates with holes in it thicker than 5mm are illegal unless fitted from the factory. Although it still seems like a grey area to me how they define spacers & adaptors.

Anyone shed some light on this?
