911 Vintage Parts is now a Wassner dealer so by extension so is Supertec.
We have rods and pistons in house for evaluation and testing. A cursory inspection indicates a very high standard of manufacture. As testing goes on we will forward our finding to the Porsche community.
One interesting note: I was informed that custom rods ordered through Wassner USA will actually be made by Carrillo. I'm not certain how or if they are connected, I just found that response interesting.
One of the first sets of rods we ordered was extremely high quality but was built to a spec that didn't fit any production Porsche. I knew what the "spec" was going in but really thought the published spec was a misprint. It was not. The rod was as advertised.

Any relation to Wössner aka Wössner Kolben GmbH ? If so, they'll be good. Have experience using their pistons.

[Henry Schmidt]

Experience shared can be invaluable.
What experience do you have with Wossner pistons used in an air-cooled Porsche?
Any experience with the Wossner rods?

[Lapkritis]

Experience is with VR6 engines related to those in the Porsche Cayenne. Bore increase +2.5mm, drop compression 1.5pts, add turbo charger for significant hp boost. They're a bit more expensive than JE/Wiseco but come standard with skirt coatings. Same alloy options as JE. 4032/2618 T6.

They've been manufacturing for awhile now and have a reputation for superior quality in the wider motorsport community, hence the higher price.

I've heard from the 944 turbo community that Wössner pistons are really good, second only to Mahle.

The 'stock' 3.0 litre pistons are not too bad and a very cost effective but we don't think they are as good as CPS or Omega in terms of detailed finish.

In particular the coating is quite fragile and doesn't compare the Moly Phosphate coating used by Omega.

We have used a number of sets but I would use Omega for competition engines.

We have had rod clearance issues with the stock 81mm 1968 S piston and had to modify them to clear so we now use CPS pistons for this type of engine

Great input Chris. Always great to hear from someone with personal experience.

We look forward to your shared personal experience as well once you have a chance to actually use their products beyond inspection. Unless you have that experience and it wasn't shared in your first post.

Does anyone know if the Wossner rods are supplied with rod bolts? If so its not such a bad price once you consider the cost of resizing the big-end and perhaps rebushing the small end.

ARP rod bolts

If they're made by Carillo, should be in good hands. Carillo makes good stuff.

The world is getting pretty small. Carillo has been owned by Pankl since 2008. There is no disputing Pankl's reputation for quality motorsport components. So if CP Carrillo is partnering with Wossner with the support from Pankl, you pretty well have all the big names in engine internals together in one place.

That's a lot of background and research cross-pollinating!

I believe the quote above is being misinterpreted. What I said was that "I was told that custom ordered rods... were made by Carrillo". That does not mean or even suggest that off the shelf Wossner rods are the same.

It is entirely possible that Wossner has a production requirement (minimum number) and that custom order rods fall short of that minimum.
