Default Hub centring rings: plastic or aluminum? Opinions.

Talking about the rings set into after market wheels to centre them on the hub/axle, in addition to the bolts. These are said also to cut vibration.

Problem: they come in plastic or aluminium.

My own thinking is that plastic might cut vibration, but aluminium would not.

Am I missing something about the wonders of aluminium?

the vibrations would come from the wheels not being properly centered - not due to some dampening provided by the ring itself. the wheels use the hub to center the rim, not the bolts so IMHO I'd want the harder material.

I agree with what mt6127 says BUT.....

I've read ad for these things.

Considering the forces involved in hold a wheel aligned on the hub I don't personally want the job done but either plastic or aluminum. I want a wheel that fits. My first thought was that if aluminum can be used successfully for wheels then the Al spacer should work, but upon reflection I decided that if their wheels don't fit then just how well do their spacers work?

Honestly, I have not bought aftermarket in years but I would look for wheels made for my car - not "One Size Fits All (sorta)". Just me.

Hub-centric wheels are superior to lug-centric at putting the wheel exactly where it belongs. The big drawback is that they can rust onto your hub and making tire changes difficult. Put a dab of grease on the hub when you install the wheel, and probably the harder metal would be the best. Plastic sounds like a bad idea. Cushioning vibration is the suspension's job, not the wheel's job.

As stated above, if possible, find a wheel that has no spacer at all. But if you have to, get the metal one, not plastic. A plastic part can be deflected by the lugs if not machined perfectly, which defeats the whole purpose of hub-centric in the first place.
