Guys,

lost my hub adaptor rings / centre bore locator / hub localiser what ever you want to call them. Did some research and there really isnt any thread stating the exact measurements. thought this would be helpful for people getting after market rims and need measurements asap for rings(save you taking off ya wheel and measuring).

So far i found a measurement of 67.1mm for the magna 3rd gen hub ring size. lost my vernier calipers so i couldnt measure exactly myself. can some enlighten, confirm or correct this please.


Cheers,

Found this on the webs


Make Model

Mitsubishi 3000GT, Diamante, Galant, Eclipse, Expo, Lancer LS/OZ, Mirage, Outlander

Inner Diameter 67.10mm

Yep it's 67.1mm.

But if you are using self-tapering nutes, you don't need them, as the rim will centre itself when you tighten them up.

Just did the measurements, (found my veniers so accurate)

i got 67mm for the hub (so 67.1mm yes)

FYI my after market BSA wheel has a 73mm bore. seems to be a standard after market size

Yeah thats right, why i haven't worried about the adaptors for ages. But the rings would take the load off the lugs and back onto the hub?

It is a very common misconception that the hub is supposed to take the load, but this is simply incorrect.

The job of the hub centre is to simply ensure the wheel is centred relative to the hub face when it goes on. When the wheel nuts are tightened, the clamping pressure creates friction between the rim and hub face. It is in fact this friction that bears the bulk of the load, not the wheel lugs or the hub centre.

Let me put it this way, even with OEM wheels and hub there will be up to 1mm or so of freeplay between inside bore the rim and the centre of the hub. Therefore in order for the hub to be load-bearing, the wheel lugs would have to be bending by a considerable margin. And common sense tells us this is not happening.

If you have self-tapering nuts, the rim will centre itself as you tighten up the nuts, and therefore you do not have to worry about the hub bore being smaller than the inside bore of the rim.

Hope that makes sense.
