    What hub rings do I need?

    Just took a set of Style 42's to a local wheel shop for refinishing. I have E30 M3 hubs on my car so the 20mm offset works perfectly, however, I also need hubcentric rings and am not sure what size to order.



    Can anyone tell me what size hubs E30 M3 hubs have, what hub size these wheels are and what adapters I'll need to mount them?

    Hoping to have them installed next week and would like to get the adapters ordered ASAP. Any info is appreciated!

    Assuming they are the same as E39 style 5's (and I'm pretty damn sure they are) you need 74.1 to 72.6mm hub reducing rings.

    '93 525iT - 5-speed swap - 320k and counting

      e30 hubs and e30 m3 hubs are 72.5

      those are e39 wheels right? If so 74.1 is the e39 hub diameter.

        Sorry, I should have been more specific. The wheels are Style 42's off an E39 M5.

          FWIW, I got metal ones from "cj" on mye28, but I'm sure tirerack or the like will have them.

            tire rack sells hub rings but you need to call as they do not sell them separately on the website. If you call them this is who you want to speak with Doc Horvath The Tire Rack 800-428-8355, ext 665

              Or just order them from ebay for 8-10 bucks for a set of 4. Example...
