I received my alledged 10mm 'Hubcentric' wheel spacer (as titled on ebay) and i noticed they dont have the center lips on them like my 15mm hubcentric spacer has. Did the chinese man (from NY) send me 'wong won'? I wanted to get my facts before i light him up with an email about sending the correct one. i know yet different from out XF's, ive seen on a google search and skim that other forums are saying 10mm is an odd size and to go with either an 8mm or a 12mm as there should be atleast a 10mm hubcentric lip on 12mm and up spacers.
