Rota Subzero - hubcentric rings?

[hp12c]

Do any of you guys have hub-centric rings with your subzeros? I am running without them for now because they are back ordered/unavailable and am experiencing (as expected) wobbling on freeway speeds. These wheels has been carefully balanced twice and the car has recieved an alignment.

I got my subzeros 17x7.5 @ 48 offset from Serious Auto.

Hrm...I just ordered the same wheel from the same vendor. Fortunately mine are not going on the car til April so I have time to resolve these issues.

I would also be interested in this issue. Please report your findings.

Best regards,
--Greg--

Edit: OK, since I'm not working today I decided I'd call Serious Auto and get the official word. The guy I spoke to says that hubcentric rings should not be needed for the WRX. Also, any vendor should be able to get you the proper hubcentric ring, should you need one.

Funny. I am having my tires mounted on my Subzeros right now and have been using the search for answers to this same question. All I have been able to find is this thread.

I didn't even know what a hubcentric ring was until I read this thread and got curious. Now I know, since I'll be buying my tires at Discount anyway I'll figure it out then and hope that they have rings that'll fit if need be.

What kind of lug nuts (and what size) are you subzero guys using?

The Splinedrives on Summit Racing are 12x1.5 but McGard's website lists all Subarus as 12x1.25.

Bunuel:

I'd be interested in hearing your observations after the install. My steering wheel shakes (wobble) a little bit at freeway speed but overall the car is riding fine. Either way tho...hubcentric rings are absolutely neccessary...don't let anyone tell you otherwise.

TyrannoSullyRex:

I am using stock lug nuts...you don't really need to go aftermarket, unless it's just for looks.

You know...Serious Auto tried to tell me the same thing...and guess what? They are wrong. The hubcentric rings are neccessary, because my steering wheel is shaking as a result of not having it. I have brought this to their attention last Monday and have not heard any word from them yet. I called them last Friday for an update and they claimed that they were "working on it".

I just made a call to discount tires...they are sending me a set and will arrive in a couple of days. I just don't know why it would take them a week to "work on this" and have no results.

When i had my 3000gt, i had rims put on and didnt remember see'n any rings....so when i put my gold dronnel dpowers on (18's) on my rex, i noticed those rings, and i asked what they were, and he said they prevent vibration...

[Bunuel]

I knew before I bought these wheels that any wheel with a larger bore needs an O Ring. I didn't know until my wheels arrived that I would need them for this wheel. I wasn't planning on putting them on my car until I could find some but wanted to have my tires put on anyway. I am waiting on a response from my vendor and will contact Discount Tire also as soon as I can get the measurements.

Do you know the exact size you ordered?

I put 17" subzero's w/225/45/17 Kumho 712s on my car last week. I did not use any hubcentric rings and I am NOT getting any shaking or vibration in my steering wheel at high speeds (up to 90 mph). I swapped out the stock lug nuts for the one's Imprezer was selling a while back though. They seem to have a bit longer tapered area than the stock lugs. I don't know if that made a difference though. I also tightened the lug nuts w/the wheel in the air since i noticed they weren't centered and would have to be centered by the lug nuts.

However, if given the choice, I would definitely use hubcentric rings if I knew where to get them.

[Senger]

Another thing...

Are the stock wheels (2002 wrx) hubcentric? It doesn't seem like it to me but I might not know what I'm looking for.

Ditto that! Sounds like cheap insurance to me. Even better, can you order online or do you have a part number?

--Greg--

[Bunuel]

Ok. I got my wheels with tires mounted. They look great. I just talked to Discount Tire and ordered the rings. Here is what you are looking for:

Subzero bore-67.1
WRX hub-56.1

part number at Discount Tire is 80881
cost me $13 shipped. Shipping out now.

Just what Bunuel wrote:

I got the exact same...hope they will fit right. They are sending them overnight, so I should be able to put them on by Wednesday and will let you all know the outcome.

They took the dimensions from the Konig Subzero...they're suppose to be the same as our Rotas.

Senger:

Our stock WRX wheels are made specificly for the WRX...so they don't need any rings to fit perfectly.

Having to use hubcentric rings is common among aftermarket wheels...but certainly, it is not "ideal".

Senger:

The aftermarket lugs you have might help...without seeing them, I really can't tell.

Since, all four wheels have been carefully balanced twice...I've ruled out the possibility that they might be inherently flawed.

BTW: what kind of torque are you guys using for the lugs? I am using 80 lbs

This is good, good news! Will you please let us know how it works out when you get them installed? I won't be needing them until the spring but better to get them now...assuming they work

Thanks,

I have a set of Subzeros on my MY00 RS. No weird vibration problems, although I didn't have them on for very long - two months. I've taken them up to speed and like I said earlier, no wierd vibrations. I've got a set of McGard splinedrive lugnuts holding them on.

Perhaps the tire itself is a bit lopsided in its construction? which is causing the vibration? I also heard that travelling at certain speeds can cause "harmonic resonance" in a vehicle which can cause vibration - a bunch of variables affect this - tire pressure, driving surface, speed, etc.

LaterZ!

My torque wrench shows up to 90 Nm (~66 lbs). I torque it a bit past the 90 Nm mark so I'm guessing it's somewhere between 66 and 70lbs. I do believe 80lbs is a bit high. The manual recommends 56-72 lbs.

hpc12-

DelicioSpeed got the same rims with the 225/45 kuhmos mounted, balanced, and alignment, he hasnt reported any vibrations.

Also he got the Kyokugen "black" racing lug nuts with the wheels (actually mach iii sold them with the wheels). these are the same ones i have on my volks, and the same ones imprezer is selling on the group buy.

good luck

[lhd type ra]

revolution motorsports has the rings

[dub976]

I just ordered my rims and they DO NOT have the rings. They are still trying to get them. they refered me to tire rack.

[dub976]

I tried tire rack when I just ordered my tries for these rims and they said that they don't have anything that would work for them.......... now what???

Read above... contact Discount Tire...

Jim

[Rattler]

I was talking to my buddy that has a front-end/suspension shop. I told him about the Rota Tarmacs I had ordered. He told me right away that if they aren't hubcentric to get the rings. Don't run them without them on. He said even if you don't feel vibrations that it could be causing other problems. He told me to contact Discount Tire if Revolution Motorsports didn't have them. I am yet to go ordere them form Discount but I spoke with them on the phone and they said they should be able to get them no problems.

[Keirik]

i'm not too experienced with hubcentric rings.....a quick question... when i call up discount tire direct..do i have to specify which kind of rings i want, or just tell them what kind of car i have and they take care of the rest?
i might be getting the subzeros also....
also...........when you get hubcentric rings.....does it depend on the rim you buy as to what sizing of hubcentric ring......or does it solely depend on the car you are driving?

is there a huge difference between getting the hard plastic over a metal one? someone was talking about the metal heating up and changing in size a little.........
thanks
by the way....i'm driving a MY00 impreza, so if anyone knows exactly the part number i need to order for my car (if it's different than the part number for a WRX) please let me know
