Is 1mm worth a hub centric ring? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

swift996 · 02-23-2013, 07:18 PM

If I read correct, the stock bore is 56.1mm.

I have wheels that have a 57.1mm whole. Is it worth it to buy hub centric rings for the new wheels?

Basically without the spacer your riding on the lug nuts alone and not on the hub bore the way vehicles were designed. not worth the risk of spending the $20. ask a machinist if 1mm is a lot.

Most aftermarket wheels (read all) are lug centric, and quite a few of them recommend to not use hub rings and they can crack from track use (i.e. enkei)

Just make sure to torque the wheels while the car is on the ground.

Should be fine without i don't even know if anybody makes any that thin.

BlaineWasHere · 02-24-2013, 04:40 PM

You're fine. That's only .5 MM difference edge to edge.

Huehuecoyotl · 02-24-2013, 05:06 PM

it doesnt matter if its 57,58 or 59. its not 56.1 so its not 'fitting', so youre no longer hubcentric

Miniata · 02-24-2013, 05:29 PM

You'll be fine for street or track duty without hubcentric rings. I highly doubt you could find any that thin anyways, and even if you could, they would be so fragile, they wouldn't last long at all.

Wheels don't ride on hub bore even if it's hub centric. Do you think those flimsly plastic rings can actually support the physical abuse?

A properly torqued lug nut will provide enough clamping force between the wheel and the wheel hub.

If you track your car, it's often not recommended to use rings because they can melt/crack. Properly install your wheels in a star pattern and torque them to the proper specs and you won't have any issues.

More info can be found in this thread.

After a little research of my own it seems your right, apologies for misinforming anyone.

You don't need hub rings if the wheels have a conical seat, making it lug centric. If you properly torque your lug nuts, the weight of the car sits evenly on all 5 studs/nuts. Many, many cars run without hub rings. Most Rays wheels come with either a 73.1 or 65.1 center bore and a lot of people don't use hub rings. On European cars you NEED hub rings because they don't use lug nuts, they use lug bolts.

Since it's only a .5mm difference get some electrical tape and wrap it around the hub a couple time. I did this to fix some vibration issues I had with some wheels meant for a VW ( 57.1 cb) since they use ball seat lug nuts.

ive been tracking my s2000 for years without hub centric rings and never had an issue. Not to say you absolutely, positively don't need them, but I'm not going to say you are going to do a lot of harm to the vehicle or yourself if you don't use them.

funbeatsfast · 02-28-2013, 04:00 PM

It may go without saying, but I'll say it anyways. Don't just torque to spec, but torque in the appropriate order.
