Does hub centric = Lug centric as well?
So if I need to ad spacers that are 6-8 mm and that is beyond the hub centric lip will the lugs center the wheel since the minimum spacer with a lip is 15mm?
Thanks Toby |

Never rely on lug-centric spacers. That's not what the studs are for. There are 7mm hub-centric spacers out there.

And from my research 15mm is the thinnest you can go to have a hub lip. I understand why, just wondering if the 911 lugs also center the wheel. |

Elephant Racing does a 7mm hub-centric spacer.

Looking at elephants website and a post by chuck I’ve come to This conclusion but could be wrong.... if your in the 8mm area your in no mans land. Not enough material to have a hubcentric spacer “with” a hub centric lip on it. Which is why I was wondering about if the lugs can act as a lug centric. |

H&r 7mm are definately hubcentric .
I moved a set in the garage a couple of days ago . I’ll have to go look in the garage but I believe ruf are too , but porsche are not . I think my next set up in size are 10mm and ruf . Hubcentric too . |

Our ball seat lugs do a pretty good job of centering the wheel. I would snug the lugnuts evenly and call it good. If it's not centered for some reason, you'll feel the vibration right away. Just my 2 cents.

Hub centric spacers take the shear loan, not the lugs
In another forum, there was a hot thread about the need to not just center the wheel properly, it is also there to transfer the shear load from the wheel to the hub, rather than placing a bending load on the studs.
