I was out for a spirited drive in the NC mountains last weekend. A rock at the apex of a corner reached out and re-arranged my rim. I got the car slowed down and parked on a level spot. Time to see how that 30 year old spare was feeling. Much to my amazement it inflated properly and didn't blow out when I put the car weight on it. Fortunately I only had to go about 2 miles back to the hotel, which I did slowly but successfully. A friend gave me a ride back to New Hill, where I picked up my truck and trailer to go rescue the car later this week.
Researching my car's receipts, I determined that these wheels were purchased out of Germany. They are 3-piece "P-Rad" or "RH 3.6" wheels. I already have a quote in hand from the vendor to sell me a replacement rim for about $300 including shipping. Could be much worse! I'll break the wheel down this weekend and confirm there is no hidden damage.
I think GMP Performance in Charlotte is still an RH wheels vendor -and may be able to just source the barrel half for you (if those circumferential bolts are not merely cosmetic)!

Depends on the damage. I had a nice set of Cup replicas on the 928 when it was bought...really looked good on the car and hit a driveway edge and zinged passenger side front.
Wheel repair place was unable to repair due to severity of damage. You just have to take the wheel to them and let them look at it.
I'm going to buy a new replacment outer rim because I'm intrigued about working on a 3 piece wheel. I've never done it before but that's never stopped me up to now

No problem!
However... you may want them to do it. There is a strong (read: special) epoxy seal that keeps every one of those bolts from being a leak. PLUS, you need to make sure the center section didn't get tweaked in the process.
RKD... on those Cayenne wheels, if the inner was bent -I'd say okay... it's not taking a lot of G-forces in cornering like a 928... but if the outer was bent, I'd be concerned about hairline cracks in the spokes. Get aggressive with a cracked wheel will put a hurtin' on ya'.
That's why I recommended the half rim replacement -unbending is one thing, but the stress damage is still there. Fine for regular, tame street driving... but not on mountain twisties.
Magnafluxing to look for cracks -and finding none- would be the only way I would ever be aggressive on a repaired wheel.
Update- I found the invoice for the original purchase of the wheels, out of Germany. I contacted the originally supplier of the wheels. They still had the purchase info. I was able to buy just the outer rim. It was a used rim but I found it to be in excellent condition, as they had polished it up so that no blems were visible. I also chose to buy a new set of nuts and bolts and the sealant that they use to seal the wheels. Shipping was by DHL and took about 2 weeks. I recently reassembled the wheels after consulting a few how-to articles. One by Pablo (via Flussig) and a youtube by Black Forest Industries. The only hard part was torquing the nuts. I had to have a friend help with that by holding the bolt heads steady while I torqued from the other side. The wheel is reassembled, sealed, and ready to mount a new tire.
All assembled and looking good.
I torqued in a star pattern, marking each one with a marker so as to keep track.
The black strip is the seam between the wheel halves that is sealed with sealant.
