If you are trying to fit wheels with a different centerbore diameter but also require a spacer, this is the solution for you. This will accomodate wheels with a larger centerbore on a hub with a smaller centerbore. For example, E39 wheels use a 74.1mm centerbore and E36 wheels use a 72.56mm centerbore. In order to fit E39 wheels on you E36 you would use our centerbore conversion spacer to make up the difference and ensure a tight, proper fitment.
