I'm trying to score a used set of Advan RGIIs, but these aren't made for our cars and I read here on NAM that a custom set of centering rings are needed.

Will it be difficult to find a place to manufacture a custom set of rings? Can anyone recommend a place in SF bay area (or anywhere else) to get these made?

Is it true that centering rings are only used to center the wheel when mounting and the rings are not load bearing?

Thanks!

 

The rings are NOT load bearing ...
The local Americas Tire and wheel works have a HUGE assortment of rings...
A known inner and outer diameter and rings to fit will work.
Even a "double ring" as used for centering could be used.
I do have "connections" in the machining word, local to both you and I, let me know if you can't find what your after.
Some really serious track / race folks have had issues with the lug nuts / studs flexing under HARD braking (picking up bounce, out of round, unbalanced situation) so a large diameter stud / nut wouldnt hurt if you had to get creative with rings.

 

Or you could just ask a dealer that carries the wheel to get a set of rings.

 

Thanks for the info! Looks like I'll be picking up the wheels on Friday. I'll just hit up the local wheel/tire shops and see if they have rings that'll fit.
