zgeezer Posted June 4, 2012 Share Posted June 4, 2012 Ok, I need help with the math. I have a set of aftermarket alloys that I ran on my Mazda mx5. These wheels are 7 inches wide x 15" with an offset of +38mm. I understand that the stock '71 Z offset was +10 The bolt circle for the Mazda alloys is 100mm; my datsun is114.3 mm I have located billet adapters from 114.3 to 100mm.. The adapters are available in two different widths: 1 inch and 2 inches. Am I correct in calculating that I would need an adapter that would be 28mm ( or 1.1024 inches) thick.. Here are the adapters I am considering: adapters Please comment. g:unsure: Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted June 4, 2012 Share Posted June 4, 2012 You might actually be better off trying to zero the offset, so 38mm = 1.5inch spacer/adapter. They would look much better and fit fine. That stock +10 doesn't really mean much since you can tuck it much more under the fender, and those wheels were thin, 6" I believe. Quote Link to comment Share on other sites More sharing options...
