Heck yeah I would get them. I suggest you don't go cheap on it. Just in case I do have aluminum hubcentric rings for sale since I can't used them on my current rims. Interested?

Most aftermarket wheels have a different inner mounting diameter (73.0mm for the most common 350z/G35 wheels) than our hubs which are 66.1mm. This difference means that without a ring, the job of holding your wheel on and perfectly centered on your hub is done by the lugs. This isn't exactly bad as that's the point of having lugs properly torqued. But because you are going to be driving over bumps, taking turns, and etc, there is a good chance than it will put extra lateral and direct loads which can cause your wheel to wobble the slightest bit.

Hub rings fill the gap and minimize/remove any movement your wheels can have with driving. This will prevent high speed wheel wobble which will transfer to your steering wheel.

I'm partial to the Aluminum ones sold by Z1 (check wheel/tire vendor forum). $29 shipped to your door. The plastic ones do the same thing, but again, I'm not so confident that plastic will hold up.

Numbers are flipped. 73.0mm for the aftermarket wheel, and 66.1 for the Z/G hub.

Aluminum ones are so tight they can get stuck. Rings are not needed.

The Aluminum ones i got got rusted onto my hubs after one season (5-6 months) and i have fully sealed center caps on my wheels. I'd personally advise to get plastic ones instead.

Uhh...rust is a conversion of iron and oxygen into iron-oxide. Aluminum by basic chemistry does not rust. Unless your rings aren't actually aluminum, then there is no way they would rust. Aluminum can corrode into an oxide form, but it does not look like rust.

Interesting info. It could have been rust already on the hub then, since i had to sand them a bit so the hub rings would fit and i guess i didn't do that good a job getting all the residue off.

But yeah aluminum does corrode, the chrome coating on mine are gone so they just look like half rusted milky grey rings stuck to the hub and rotor lol

Plastic hub centric rings will melt if you use your car on a road course.

Nt03 do not have a 73mm bore. Yes you should fit rings to avoid hi speed vibration and we can supply the right ones for that wheel

aluminum rings do not corrode at all the hub does though. Depending on the weather they are subject too , especially salted roads the color can be eaten away but the ring will stay intact.

if i were to buy a aftermarket wheel and it came in two different hub bore sizes one is 67.1mm and the other is 73mm, should i get the 67.1mm to not worry about getting a hubcentric ring?

67.1 is center bore size for Mitsubishi Evos..

you're still off.. i would get the 73 and buy the hubcentric ring inserts from Adam @ Z1 to get the sizing specific to our Zs.

Could someone confirm if SSR wheels follow the same trend on hub bore diameter? I checked that link up top and they only had SSW wheels. Their website also did not have the information and I would like to order them before my wheels arrive.

A must buy
