Hi. Just need a little advice reference these. Recently fitted a pair of 8mm Hubcentric spacers to the rear of my Audi A4 3.0tdi Quattro. With this size of spacer the OEM wheel does not actually sit on the hub spigot. Do I need to purchase spigot rings, if so what will work? I have looked at spacers with an additional flange machined as part of it but these seem to be for spacers 10mm in thickness and over. Thanks
