Hi. Just bought a set of 4 OZ racing aero 3 3 pieces 17inch for my E 500 1994. The rear center face cracked the first day. I believed it was cracked and covered by welding. Anyone can help me to find one rear face piece please. Seller doesn’t want to have anything to do with that and I can’t use 3 wheels. Attached the picture. Appreciated. Shawn. 8589224439.

These guys are one of the best in the business, if not the best. I have used them for many years. Other members have used them as well.
Contact them, you bad rim might be able to be repaired.

Thank you so much. Will call them tomorrow. Please let me know if you get other lead.
Thank you. Do you know what kind of machine shop ? Wheel shop?
You're welcome.
googled "cnc custom wheel machining" a lot of good sites came up, this one looked quite promising. I know nothing about any of the sites/businesses.

Shawn, I don't recommend a weld repair on these wheels.
The material will weld up pretty nicely, and by using correct weld wire the strength in the weld itself can be compensated. But the heat from the welding degrades the mechanical properties in the HAZ (heat affected zone) - along the edge of the weld. This means the weak point is just "moved around", to put it in a more understanding term. This is forged wheels where the combination of the chemical composition and a controlled heat treatment process makes the strength. By welding, the heat input will degrade the mechanical properties to an unknown extent. As for custom made replicas, believe me - they will never achieve such mechanical properties. Well, it can be done, but at an astronomic cost at your end.
These wheels are out on ebay year around, separate parts like discs and barrels as well. Many of them are refurbished, which is a risk because they may have hidden cracks below the new coating. The seller may not even know that the wheels had cracks prior to the refurbishment. Additionally the trend is that sellers think this is gold pushing extreme prices, with no warranty about the cracking issues. But the wheels don't sell that fast either, so it's likely the buyers market.

I never had a center cracked like this... and if i got one like this in a set of 4, I would put all 4 in parts, get the paint off and check them very carefully for more cracks!

OH yeah, here we go - post weld fatigue cracking!
I enlarged the photo and compared to a good disc, and you clearly see the weld on the backside of the spoke. This is exactly the risk scenario I was talking about in my previous post, the spoke has separated entirely from the barrel interface ring! I guess we can say that the AMG Aero OZ wheels are not subject to weld repairs.

Keep your wheels and be patient, a single wheel will come up for sale at some point. I've enclosed an image of my set showing the PNs.

You should do a charge-back for 1/4 of the sum through your bank/credit card company. Will work 100%. Don't let this go unpunished
So many of these OZ wheels have lug bolt hole cracks that anyone would be taking a huge risk buying a wheel or set of these absent any positive declaration by the Seller that the wheel(s) is/are crack free. They are pretty wheels, no doubt. I have owned 2 amazing sets myself, but would be hesitant to try and acquire another set.
Thankfully, my widebody SEC is a Gen I or I would be caught up in the OZ madness myself.

Hi. Do you still have or know who makes the center piece ? OZ aero III 3 piece 17x10et17
You can contact me t hheiati@yahoo.com. Thanks. Shawn
Shawn, the OZ center piece you need is difficult to find, even worldwide. I have no leads to finding any. Jono at Blue Ridge and bb1 are probably your best bet if you want to fix that wheel and keep your set intact.
While I love these wheels on the E500E, the fragility and high cost have permanently scared me away from them - especially if they will be used driving on public roads, not just bolted on for car shows.

Thanks. I know. Next time I read or ask about parts on the E500 board before purchasing. Direct messaged bb1 and Jono. No answer yet. Do you know there email address?Shawn, the OZ center piece you need is difficult to find, even worldwide. I have no leads to finding any.

Looks like Jono has a new website and the email addy is gone, but there's a phone number!

this one?
price looks ok....

Thanks. Checked that one. Not sure if face piece is cracked. Picture looks really bad. Thanks for your help.
Yes, that center looks to be toast, strictly based on pics provided. I’d venture to say they welded over a crack without fully removing and likely didn’t add enough filler metal. Which usually self propagates a centerline crack, from the rapid cooling /shrinkage of the molten metal.
In regards to 500AMM’s post above- well explained for the lay man to understand. I do not disagree with it. But I’m not 100% on board. I don’t believe the base material is a heat treatable alloy. The HAZ is the weakest part. There are factors such as dilution and heat input that play a role in the final repair strength. More heat isn’t always better....!
Will a repaired wheel crack again? It’s definitely a possibility.... but the quality of the repair is usually a reflection of the person performing such repairs...

Thank you for the note. I won't repair this. I can't trust it. I am purchasing a face of of eBay.
7delta, thanks for filling in on this. And you're right about the heat treatment process, I just simplified the picture a bit. These discs are forged to shape, where the parameters like ramp up, temperature, holding time, cooling etc.. is a part of the forging process. All parameters has been set during the product development, next they have to be kept controlled during the entire production process to achieve repetitive mechanical properties on each item.
Just to narrow down the common issue on welding - the base material is melted to bond - but next it solidifies ultimately in its origin condition. So if a base material/product has undergone a heat treatment process to achieve specific mechanical properties - either as part of a production process or in a separate post heat treatment process, that will degrade along the edges of the weld. That makes it pretty challenging, and the more complex the base material is, the less is the chance to do a successful weld repair.
Another issue is weldabilty, where some base materials in fact cannot be welded, or their melting characteristics is weird and don't give a sound weld. Let's not dive into that topic here, but some of the cheap casted aftermarket wheels has a very bad weldability.

I bought them from someone in east coast He said they were refurbished not saying anything about the cracks that were welded and polished to cover. After driving Less than 100 miles I heard clicking noise. There it was the cracks opened up. Luckily I noticed it before the whole wheel falling apart otherwise would be a disaster. We checked only one was welded. Other 3 are ok.
