Hubcentric ring size question

[gotboost2jz]

I do believe 240sx's have a 66.1mm wheel hub. I have mustang wheels for my car. I'm looking for the correct size hubcentric rings. I believe the mustang's hub size is 70.5mm. Can anyone confirm or deny this?
Secondly, can anyone give suggestions on where to buy this ring? JustforWheels seems bent on telling me that 240sx's don't come in 5 lug to match mustang wheels and havent given me an answer. Even then, on their sit they dont have the option for 66.1 inner diameter and 70.5 outer. Just 70.4mm outer

[Dustxking]

Call a tire/wheel company all their info should have hub bores listed. By year make modle. Clear it up for you, only problem is finding one that is made in those sizes most companys like gorilla auto that makes these only make them for aftermarket wheels aka 73.10 99% of the time.

[gotboost2jz]

In that case, anyone know of a site to get 5x114.3 12mm (or 1/2 inch) hubcentric spacers with a center bore of 70.5mm?

[6330]

S13 is 66.1 for sure.
Mustang I don't know.

[gotboost2jz]

Asked around a mustang group and the for most mustangs I gathered it is 70.5mm. Brand new ones I don't know though as well as older ones I don't know. But 70.5 should cover most all mustang wheels any of us would be using on a 240

HUB CENTRIC RING RINGS SPACERS OD=75mm / ID=66.1mm | eBay (http://www.ebay.com/itm/HUB-CENTRIC-RING-RINGS-SPACERS-OD-75mm-ID-66-1mm-/350095937118?pt=Motors_Car_Truck_Parts_Accessories&hash=item5183580e5e&vxp=mtr)
this is not the size you are looking for but you could try contacting that company and they could probably make you one.

that or contact your local machine shop

or google 66.1 70.5 od like i did, heres a resulthttp://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CGIQFjAB&url=http%3A%2F%2Fwww.uniauto-wepro.com%2Findex.php%3Foption%3Dcom_content%26vie w%3Darticle%26id%3D23%26Itemid%3D43&ei=N47OT-tTzcTQAd2r_cAI&usg=AFQjCNFvy2EkLflnMQ_ZmeeTIKMmz-vTBA (http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CGIQFjAB&url=http%3A%2F%2Fwww.uniauto-wepro.com%2Findex.php%3Foption%3Dcom_content%26vie w%3Darticle%26id%3D23%26Itemid%3D43&ei=N47OT-tTzcTQAd2r_cAI&usg=AFQjCNFvy2EkLflnMQ_ZmeeTIKMmz-vTBA)/index.php?option=com_content&view=article&id=23&Itemid=43 (http://www.uniauto-wepro.com/index.php?option=com_content&view=article&id=23&Itemid=43)

Doesn't matter anymore. I did a test fit and with spacers and the stock 240sx wheel hub doesn't extend past them so huncentric rings wouldn't sit on the 240 hub anyway. I ended up just purchasing 70.5mm hubcentric spacers. More $ and can't use my nissan spare wheels with those spacers but it had to be done.

[dawagarage]

but you do realize the 70.5 spacers have an ID of 70.5, which you are putting on the 66.1mm OD hub, right?

[gotboost2jz]

I fail to see your point. 66.1 is smaller than 70.5 so the stock hub fits well inside the hole of the spacers. No fitting issues.

Edit: I think I get what you're saying after thinking it over. It's not a clearance issue but the spacer's diameter will still be wider than the stock hub thus leaving a gap that needs filled between the two. Is that what you meant?

[AsleepAltima]

do the wheels require acorn lug nuts or the standard lug nuts? if theyre acorn, you dont need those rings.

^haha, yes thats what i mean. imagine a putting a 18" tire on a 17" wheel (blown out of proportion example.) the weight, stress etc, will not be transferring to the hub since there is still that 4.4MM of difference. so its almost as if you arent hubcentric at all.

^wtf are you talking about!? im not saying youre wrong but ive never heard what youre talking about.

these here. the one on the right doesnt require a ring and is called an acorn nut. the one on the left is lugcentric and could benefit from one. acorn nuts eliminate the need for the hubcentric ring because they center the wheel for you.

^ i know the difference in nuts but i guess i never made the connection of different nuts and different "centrics" (?) i had once read that (or misread) that "Lugcentric" was a "myth"/untrue. anyways, did some more reading. here's something to consider, even though this is now trailing off from the initial topic...

No, because then all the rotational load of the wheel would then rest on the studs instead of the hub bearing.
And while acorn lug nuts do help center they arent perfect. Very close, but not 100%. Hubcentric wheels need a hubcentric seat to rest on for both load reasons as well as centering reasons.


PS. I do have acorn tuner lugs. They're nice. But they won't do anything to strengthen the wheel studs.

[AsleepAltima]

negative ghost rider. no ring is going to override those acorn nuts once they are tightened. guaranteed. once "tuner" nuts are tightened, the wheel is straight because of them. this is a huge debate on many forums and its a waste of money when you use these lugs with the wheels that require them.

[AsleepAltima]

think about this for a minute. logically. take a wheel off, then reinstall it. put one lug on and tighten is slightly. see the wheel move? now install a 2nd one. see it move some more? when you have all 4 or 5 lugs tightened, how do you think, in any POSSIBLE way, that youre going to move that wheel against those lugs? if this doesnt click in your head, then you need to do some serious thinking.

[dawagarage]

aww i wish you called me ghost rider. but yeah i agree with all that hub vs lugcentric debate about the interwebz. i wish the google results would produce something from actual engineers and tests.

[gotboost2jz]

Agree to disagree, but that still doesn't change the fact that you're now running the risk of torsional loads shearing your wheel studs off from not having a hubcentric center to absorb the energy. Stock studs especially are NOT meant to take this kind of load. Even aftermarket studs are prone to fail under high stress conditions. Hence why you have probably seen a car or two spit out a wheel from its well while on the track.

explain to me how the wheel is going to sit on that ring once the lugs are tightened. its impossible. but id like to hear how.

lol, when i think of the word "negative" - thats the first thing that comes to mind. haha

[gotboost2jz]

how do you think, in any POSSIBLE way, that youre going to move that wheel against those lugs? if this doesnt click in your head, then you need to do some serious thinking.

Who said anything about moving it? I can torque a wheel down with standard nuts and its not going to move anywhere. But you cannot 100% guarantee a perfect center with just lug nuts. I never said anything about the wheel moving.
I know how acorn nuts work. I said I use them.
And they're not a waste of money with a centering hub. Not every single wheel is the same. My wheels have angled cut outs in the both holes that require acorn nuts, regardless of hub

ok, i see youre not thinking this through. at all. when you set that wheel onto the hub, the lug nuts will pull on it until THEY center the wheel. if you put a ring on there, regardless of the precision of the ring, the lug nuts will attempt to pull it to where THEY want it. if the wheel doesnt go where the lugs are attempting to pull it, now you have lots of tension against the studs themselves which will lead to more problems. how do you not see the logic of that?

You don't need to be condescending. I get what you're saying. I just disagree with it.

I can see what you're saying, if you had warped studs or rotors perhaps. But the picture you paint seems so unlikely. Even still, it's vastly better then no centering hub and all the torsional load being placed on the studs alone. Maybe there are cases, but I can't say I've ever heard of people having problems with centering hubs and acorn nuts in combination. And if there are, then I'm SOL because my wheels require them.
Again, I'll just agree to disagree. None of this lug nuts talk has anything to do with the topic at hand mind you.

i didnt mean to be condescending - sorry. text just makes it seem that way. i know its not exactly on topic, but the two do go hand in hand.
