"Turbo twist" is like calling sport classic II's "mesh",

A better slang may be a "4S twist" as the turbo had hollows as a
standard.

They are all called Technology wheels, solid spoke or hollow spoke.
Now the turbo S Technology wheel was hollow spoke with a special bright silver color.

Easiest way to tell the difference is in the special valve stem used in the hollow spoke.

I got quite a few Porsche books, it's funny some say the C2S came with 18in TT wheels, & some say 17in wheels with a 30mm spacer in the rear. I can't find anything in my factory Porsche literature on the C2S.

Weird, how every one has a difference of opinion on it. One book made by Haynes "Porsche Data Book" is nothing but stats on all cars, says 17in factory & 18in optional. IMHO, the 17in cups are wrong for the C2S.

In the end, what do I know.

Say, that Porsche Data Book by Bongers you mention, how detailed are the specs he gives? Does it get down to sway bar sizes, valve sizes and the like? Curious.

I was working for Porsche and doing pre-delivery inspections fresh off the boat for the C2S run. They all had 17" narrow body wheels with spacers, unless upgraded at the time of order. This in most cases was an 18” narrow body wheel with spacers. I never recall seeing a C2S with wide body wheels.

993S :
standard 17" with spacers (rear)
optional 18" without spacers, (hollow spokes with P32 sport suspension package)

Sorry it's from Haynes, not Bentley.

It has a little 2-6 page summary of each model series, then stat break downs of each model. It's general info, like bore/stroke, compression, hp, gear ratios, 0-60. But it doesn't go into detail on the engine or suspension.

Each country if not each order had different setups as per porsche.
Mine came with hollow from the factory as standard. England and Germany had 17's on the S (IN GENERAL)
There are times where economy, weather, fashion, style etc differ from state to state. lets take the following as an example:

Porsche 997 turbo S price in England = £ 125.865 = €142.857
http://www.porsche.com/uk/models/911/911-turbo-s/
Porsche 997 turbo S price in Germany or France= € 173.241
http://www.porsche.com/germany/models/911/911-turbo-s/

that's €30k or $42k difference.
So basically i can go in 2 and a half hours ride to London, and order a Turbo S and save 30.000 euros
But the economy in england is dreary, so.....
So maybe the Turbo S delivered in england has a few things less as standard than the german one etc.
(and yes you can order a Left hand drive in england from dealer)

I understand C2S here were delivered with 17" cups as standard, with solid 18"s as an option. Only turbos and possibly C4S's had the hollow spokes.

TheMirror

OK, Whew! So it's nothing like this then?

Stealth 993

Yea, it's the same, just with out all the little details. I'd say the book has about 1/4-1/3 of that info.

My C4S has the two grooves on the back of each spoke but metal valve stems. The original owner must have put the metal valve stems in the solid spoke rims.

Ah, thanks. I'm glad you could see that screenshot, I have it hosted on Squarespace which isn't the best venue for embedded images.

Reviving this thread to see if anyone knows for sure if "technology" means hollow spoke on a C4S ? My options list says "technology" but the wheels are solid spoke (grooves behind spoke ) so..changed by PO or technology could still be solid/turbo twist ?

JPP

No. The proper Porsche factory name for the wheel, hollow or solid, is Technology .. as you've said, the solids had the casting grooves on the back of the spokes and the hollows are smooth because they're .. well .. hollow!

Shtootgart

Thank you. Do you know if the wheels are numbered and matched to car (by VIN or something) or can I buy P-car's and simply be "good as new" ? Mine have a bit of wear and I'm trying to figure out what it will cost to refinish vs. swap out
