There is stock of rears in Germany, there are no fronts in stock

I'm after a set of hollow spoke wheels. If the turbo s ones are cheaper should I be looking for those or is there a difference other than the finish?

Olly, according to 911Pervy (who very often has seriously valueable information), only the TurboS rears are in stock. So they appear to be cheaper yes but you can't buy the fronts new so what's the point? There are no differences other than the finish (and the part number). So your best bet is a set of used hollows. Look in the classifieds, there are a few sets there for sale. GL.

If you want new on the rears you have to go turbo S and get them refinished in silver paint as the silver painted versions are NLA! Crazy thing you save £500 a pop!

993TurboS,

could you please confirm the wheels you are talking about are from a genuine turbo s Code 993780 not 770? And the number 911Pervy has posted is that a number diecasted in the rear of the rims? What else is diecasted in the rims beside the size and material? There should be a box which on the turbo wheels gives the mfg date as 2 digits in the left, with 12 dots in two rows to the right of that indicating the month of mfg and below that "sm" standing for the manufacturer? So those rims than should show a different manufacturer if my research is right.

Or was it just a number on a box.

I am asking for the following reasons:
I do have a genuine 993 turbo S "993780", delivery in Germany with 450hp and year Feb. 1998. However the wheels have been painted at some point. The number on those wheels diecasted in is the "normal" 993.362.136.00 and 993.362.140.00 , the same as on the hollow spokes of my 993 2S. Also 3 of the 4 rims on my turbo S where mfg in 1997 (also diecasted in) which seems correct for my MJ 98. It would be very odd if someone later would replace wheels and by accident gets from the factory several wheels all made years ago in the same month... Also I do have all invoices of all inspections and repairs I know of, and one of them lists the resurfacing of the rims, and the last owner also admitted replacing a wheel. So I don't believe 3 other wheels were exchanged if both previous owners whom I both do know deny that.

Having said that, ...980... indicates a number from the exclusive department which makes sense.
Also I spoke to a design manager and he to his colleague, a former Porsche account manager, at rim manufaturer ATS, who bought "sm" (Stahlschmidt & Maiworm) who pioneered the hollow spoke system, and who claims to have made ALL Porsche hollow spoke turbo twist wheels. He knew exactly the aluminium deposit "sputter" process but has never done it for Porsche, and he claimed that noone else would have had the technology to do hollow spokes back then.

So the post of geolab - where he explains the sputtering process - but also said that a factory in the east of france not just did the finish but also made the hollow spoke rims themselves is a bit of a mistery to me, I have assumed that Porsche maybe sent the rims of sm to that factory?? But then the diecasted numbers would have to be the same. So if that factory in france actually made the rims, and that factory is not a subsidiary of sm, than the rims should show not sm as manufacturer (which unfortunately would also mean I have two sets of wrong wheels for my turbo S...)

So 993TurboS please verify that your rims have the ...980.04 and ...980.05 numbers "casted" into the inside of the rims and then please also state if there is a hint as to the manufacturer below that box with the manufacturing date or elsewhere.

And as to the surface, I guess any sort of painting will not do it. They were "sputtered" or IVD (ion vapor deposit) treated as geolab explained it very well, and I have found noone up so far who can do that. There used to be a guy near Dresden Germany who did this, but his quality was poor and the aluminium flaked off. And I was told, if there is a scratch to the surface it has to be sealed again with clear coat, otherwise moisture might seap in and lift the aluminium off.

Best regards

I'll get around to this at some point, but it sounds like it'll take some effort. I'll post here once I know. I have two sets, one that came on the car and have to be correct. Those are the ones that I have had sitting. The others i acquired 6-7 Years ago through what i believe was the original supplier of the wheels.

The two sets look the same to me, but I have never looked at the part numbers.

A guy on rennlist used to own a bunch of turbos and turbo ss and he apparently got Protosport to find someone who could recreate the finish. He redid wheels that came out perfect from what I have heard.

Turbo S do you have the Turbo S center caps as well?

That's probably someone here offering mine with the plan to buy them from me for 3000 and resell for 10000!

I do have the caps on both sets.

993TurboS,
which rim would you say looks more like the rims you have for the turbo S.
The shiny one ("chrome look") on picture one, the rather normal or matte looking one in picture two, or number three, which a German rim refurbisher claims to be a genuine turbo S rim on which he just polished the outmost 2cm near the tire?
Thanks

993TurboS

1 and 3 don't look like turbo s wheels to me. Real ones look like 2 to me. I think i posted close ups somewhere on rennlist. In any case, mine look just like all of the other turbo s wheels you see on original Ss.

993TurboS,

thanks a lot! That confirms one of two very opposing but both very credible sets of opinions I am getting on this...

Getting to be more of a mistery the more I dig into this.

Would be very interesting to see what numbers are casted into your rims, but I am betting a genuine German Weissbier that the number casted in the back of your rims is not a ...980... number but the "normal" 993.362.136.00 or ..140.00" ...
If you can prove me wrong, than this gets even more of a mistery and I owe you a Weissbier or a Liter ("Mass") of bier at the next octoberfest...

And as to the wheels for sale by LA Dismanteler, they have not yet answered my questions if they in fact are unpainted, a picture without center cap, number casted in the back etc. Good luck to them. I wonder if they are now salavaging the silver turbo S they had (or still have?) for sale (at if I remember right 189k?), on which these wheels still seem to be, which was already missing the carbon strut brace and god knows what else. But why would anybody salvage a turbo S , I would have thought this is a classic example of a car that today is worth more than its pieces. And if they still want to sell that car then with what wheels? Recreated ones?
They also have a badly scratched turbo S front wheel for sale which no-one would put like that on his car and for which they ask 800$ ... Again, if they are aluminium vapor finish, no-one can do it anymore. If they are high gloss paint, any scratched hollow spoke could be painted ... unless that ..980... number would be in the back which is what I have yet to see.
