These 20mm hub adapter/spacers are to suit BMW with PCD 5x120, centre bore 72.5mm and M12x1.5 bolt thread. Just type in BMW hub size into google to see if these will suit your car. Fine for e46, e36 etc.
These are spacers that bolt, supplied, onto your hubs then your wheel bolts into the adapter, so no need for longer bolts.
Add some stance to your BMW for only £35
