Okay did some research.
Oem is 12mm x 1.5 bolt----bore is 66.6 factory-hubcentric spacer should be 66.5 for perfect fitment (avoiding any wobble issues) and of course the 5x112 bolt pattern.
So my options are the 12mm by 1.5 or 14mm by 1.5
I would assume the 12mm is the diameter of the bolt and the 1.5 the length???
Or...is the 14mm option indeed the longer bolt.
Daunting task these spacers....
Anyone with this set up have a vendor...
