Hey everyone, I've been stuck with this problem since I bought the wheels 2 months ago.

Any tips/advice for Brabus Monoblock IV's? - MBWorld.org Forums

I get vibration in the steering wheel and the front seats after 45 mph. I was thinking hub rings, but I had my hub and the hub bore of the wheels measured and they were supposedly the same size. I still don't believe the guy that measured them. He said it was from the "taper" that these wheels had (in the other thread, you can see that the back of these wheels don't exactly look like most others). Anyways, when they are placed on the hub, they rock back and forth instead of just sitting there like they should. I'm pretty lost and don't know what else to do Any pointers?

Shall we be flattered?
Fact is that several handles there sounds familiar.
I do have experience in precision mechanics from my other life and have to point few things.
The MB wheels are hub-centering, so the hole in the wheel is critical.
You have unknown condition wheels matched with unknown quality centric rings.
The rings would be the easiest start of checking. Do they fit with no play inside the wheels? If you can remove one - does it have tight fit on the hub? When it goes easy on and off - the clearance is too loose.
When the rings check, do the wheels test. You posted picture of tire marks on your suspension. Lay down under front bumper and see if the tire is rubbing with present set up, or are those marks from possible past?
Than it is possible that the rims are bent, but that is something balancing guy should catch. Did you have tires mounted at reputable shop?
Side advise, I just switched from balancing weights to pellets inside the tires. Looks like I will never use weights again.

Haha I've been part of both forums for a while, just been a little more active over there.

the problem is that I don't have hubcentric rings in the first place. It's been really hard to find information on what size I need. And I think the tire was rubbing with my previous wheels, because they had a higher offset.

I had my wheels balanced twice, and neither of my tire guys said that they were bent. I think I might take it to Wheel Techniques in Santa Clara, but that won't be until late November, because I'm a college student out in Merced

So did you at lest put some bubble gum to hold them from playing around?
You might be student, but there is no excuse for endangering your and other road users life while driving on not properly set wheels.
Any qualified shop should set the rings for you over the phone, or at least that is what I would expect.

That's exactly why I'm trying to get this solved as soon as possible. I understand that it's unsafe, which is why my car sits in the garage most of the time.

Would I just be able to call a reputable shop, tell them that I have Monoblock IVs, and order hub rings?

That is what I would expect. I take it you never tried?

Since the issue has been going on for a while, rather than just ordering some hub-centric rings, I would suggesting taking the car to a competent tire and wheel shop and have the wheels and hubs inspected to be sure you haven't damaged anything. If you also have them order and mount the rings, should you then have residual issues you can return to them for satisfaction.

Good luck.

I'll give Sonic MS in Mountain View a call in a sec.

I'll get them checked by a wheel shop in the Bay Area the next chance I get.

Called some of the most reputable shops in the Bay Area, Brabus, and Otis inc. and none were able to help. Thanks to fellow members BADwayz and jserio, I was able to find out that the center bore was 76mm, so I need 76-66.6mm hub rings.

One more proof that this forum can help when professionals are .... not so professionals.
I wonder if you will find wheel shop that can order the spacers for you, or would you have to go to amateurs again.
Sorry I guessed bad about professionals.

Hey! I'm guilty of that as well. I first signed up with MBworld and after a few days, I found that I was talking to a wall. This place is awesome! People share ideas and their own experiences. Lots of people working on their own gear.

Can you forgive me?

definitely. I've gotten so much more help here than I have there. I've even sold 2 sets of wheels through here! It seems like people on this forum are a lot more involved and willing to help. They're also more open about tasteful mods!

 

[siopaolover]

not too sure how these hub rings fit in the hub bore...

 

[Kajtek1]

The way you hold it you should put it on the hub. Meaning at this time it is backwards for the wheel.
Is it metal or plastic?

 

[siopaolover]

so I put the 76mm side first? that makes it so that I have all of the 66.56 side hanging off the wheel, so it works like a wheel spacer. because of that, I can't bolt my wheels up because my bolts are now too short

 

[Kajtek1]

The ring should go all inside the wheel hole, still allowing full contact of the wheel with the hub. This is where factory wheel mounting pin in your tool set becomes very handy.
I hope you did check the bolt length while installing the wheels first time?

do I put the ring in with the 66.56mm side first? i tried putting it in that way, but it did not go in. maybe use a mallet?

and I had accurate measurements and everything for the bolts. I had Phil from Otis Inc LA on the phone while I did my measurements.

 

[siopaolover]

I figured out the way it's supposed to go in, but I can't seem to actually get it inside the hub bore. am i supposed to press hard on the hub ring to force it in?

 

[siopaolover]

UPDATE: I unmounted my wheel again, but the hub ring does not fit inside. It matches the 66.56 part of the wheel perfectly. could there possibly already be an aluminum hub ring that just needs to be replaced? I'm completely out of ideas
