Will be hard to inspect bushings as they are obstructed.

After fixing my cayenne which has similar noises, thst users ovserve and repair, i would tackle these noises in shown order.

I have diy on sway bar bushing repair on here in cayenne section, i think.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Spent an hour reading guys... My apologies in advance if this is a re-hash violation (I do try):
Just got my 19" OZ's back from the powder coater. Saw the obvious damage to the seal at about wheel center interior. Took them to the tire shop for the inaugural mount of my $2k worth of Tire Rack tires (don't get me started) with fingers crossed. Told them to keep them overnight to see if they sealed. No such luck on the rears. They're peeling them off today and I'm tasked with the resealing job I guess. Went on the OZ site and see that I'd be writing a question to Italy so haven't yet. Before I attempt silicone on my own I figure I'd run the question by the experts? Thx in advance... Gregg
Yikes... sorry to hear about that. I have heard that powder coating is a high-temperature process and that it can easily damage wheels and/or weaken them if the temperature isn't precisely regulated during the process. It sounds like you may have run into that problem. Hopefully the powder coater will do the right thing and reimburse you and/or replace the damaged wheels.
I was afraid of that FLA996TT and apologize for being vague. Here goes...
The SUPERLEGGERA is a 3 piece wheel as you know. The barrels join and the factory seals them with what appears to be a wet painted on seal in the assembly/manufacturing process. Powder coating has it's way with that seal. When you look at the backside of the wheel it's pretty easy to see what I'm talking about. The bead seal is likely not the culprit after being evaluated by the tire guys. Assuming I can just run a bead of something with success, it shouldn't be too tough. Hoping that someone on the forum has been through it (I know this must be the case).
Clear as mud?
To put some finishing touches on this thread, there are few things that can make sounds describrd. Each has to be looked at, or uf u do full bore approach, do all at once to fix sounds issue.
1. Lower control arms - known culprit, squeak or thud when going over bumps. You can inspect and see bushings tears. Fix is to replace control arms.
2. Upper control arms - known culprit, squeaks over bumps. Will be hard to inspect bushings as they are obstructed. There is process to inspect on cayenne section. If you replaced lower control arms, and sounds still present, replace the upper control arms. Plus read next point.
3. Upper shock mount bushings - known culprit in air suspension, clunking sound over bumps, especially low speed. These are rubber stops inside each shock. They are supposed to keep internals aligned, but if they get worn, internals of shock stary flopping around, hence clunking sound. Remedy is to replace said bushings. I have a diy from cayenne section on how to do this. Not hard, and if youre doingupper control arms, you have to remove air shocks, giving you perfect opportunity to to replace.
4. Sway bar bushings - not as common for squeaks. Easy to replace, but i would do thease aftervabove 3 are addressed. I have diy on sway bar bushing repair on here in cayenne section, i think.
5. Sway bar links - not as common for squeaks, easy to replace. If i reolace sway bar bushings, might as well do th ese too, cheap and need removal to change sway bushings.
After fixing my cayenne which has similar noises, thst users ovserve and repair, i would tackle these noises in shown order. Very doable as diy.
Great minds... As you see from the photo in my avatar I've owned a fair number of various things for the track. My guys will be good resources moving forward. Still dreaming about direct expert experience from the community though!

You need to find a wheel manufacture that does that. There is a place in new Rochelle ny called proformance that does that. I have had many repairs done by them. I'm sure u can send him your wheels and they will fix them properly. Ask for Mario [phone removed] hope that helps
You need to contact a a place that manufactures their own wheels. Call Mario at Proformance I'm sure u can send him your wheels they are located in New Rochelle NY. The number [phone removed] I have had many repairs done by them. The power coater was supposed to disassemble before power coating and reseal after.
The place that did the powder coating was supposed to break the seal power coat the wheels and rebuild the wheels when u bake the power coat on it melts the bead

I'd like to hear what the factory says! I know powder coating can damage things if not done correctly but I would have to think the factory would have engineered in some tollerances given the high propensity for owners to mod.
Quote:
Given this...I would say a speed shop or good wheel shop could do the repair for you. This IMO should be an easy fix, just make sure the shop KNOWS what they are doing as I imagine if they rebuilt them incorrectly they could throw the wheels out of true.
If it were me...Local Porsche dealer or experienced indy as alot of indy shops also race.
I don't know OZ's process or composition but BBS uses rubber seal rings sandwiched between the barrels.
I would call Damon at Tire Rack and he should be able to get you some help. He's not only the Porsche tire rep there, he's also an owner.
Btw, with as much lateral forces the wheels see, I wouldn't chance just trying to stick silicone in there. The really need to be taken apart and reassembled all PROPERLY torqued.
Ask me how I know...
What needs to be done is repeat the original assembly process. Disassemble the wheels. Clean throughly, reapply oem type seal. (may be silicone sealer, may be O-ring) Reassemble, usually new bolts required & torque to spec in proper pattern. And yes the bolts are not cheap!
Quote:
I'm not sure if OZ uses one time use wheel bolts or if they sell to the public. I know BBS doesn't sell wheel bolts to the public for liability reasons.
Good luck OP. PM me if you have a hard time finding bolts. I have a couple sources.
I watched a youtube video on the manufacture of 3 piece wheels... can't remember the manufacturer??
Anyway, they just applied some sort of silicone sealer (like you would caulk a bath tub) where the two pieces of the wheel met...
I don't know if the silicone was special or not??
This is a source reference. Confirm exact model applicability in the original material.
