You obviously have not ever examined the 1976 911 , Carrera , Turbo price list.

Nowhere on the page you posted , from a 76MY owners manual , does it state that the 6 & 7 in wheels referenced are forged. It is refering to the ATS cast wheels. Neither does it state anything about the specific options that get a car delivered with specific wheels or tires.

So , you think both the price list (with specific descriptions of the options) and the parts books are wrong.


Again , on the price list , BOTH the 7 & 8 in. forged wheel options specifically state 185/70VR15 & 215/60-15 tires. And the 50 series tires option does not mention wheels at all. And why do you think that a specific speedo , specially calibrated for 50 series tires on 15" rims , existed with a separate unique part number.


Why don't you try reading the material I referenced. You are making a determination without taking into account all the documentation.

I don't understand where you are coming from or what you problem is but isn't what you are trying to say the same thing that I said in post #17

I did read what you posted and your version of the facts don't jibe w/ my recollection or the documentation that I received at purchase, I posted the page from my original '76 C3 owners manual which outlined the available wheel and tire combinations, I can post the same info from the shop manuals, what more do you want? It seems that you want to fight about something that is uncontestable, regardless, I give up and you are welcome to your fantasies

for the record, I never said that the stock wheels were forged, they were the pressure cast ATE cookie cutters, 6 & 7 x15 w/ 185/60 & 215/50 tire

there were 3 wheel/tire choices for '76 C3

option1 was forged Fuchs 6 & 7 x15 w/ 185/70 & 215/60 tires, these were the stock setup on '73 2.7 RS

option 2 was forged Fuchs 7 & 8 x15 w/ 185/70 & 215/60 tires

option3 was forged Fuchs 7 & 8 x15 w/ 205/50 & 225/50 tires, this was the option that came on my C3, and yes the speedo calibration was specific to these tires, if you want to call this 3 separate options, fine, if that's your point than you win as the king of the nitpickers

Your not getting it , all i'm saying is that in all the literature that I can find (both factory and outside review).

For 1976 , it shows the 50 series 15 inch tire option (m395) is for the tires only , at a cost of DM800. Maybe they left off the text concerning the wheels. This price seems pretty expensive for just tires . But at that time these tires were almost a brand new design. , so it's very possible they were that cost alone.

Here's an excerpt from a write-up by Michael Cotton concerning the 1976MY 930 :

"For the 1976 model year (commencing August 1975) Pirelli P7 tyre equipment became available at a quoted extra price of DM 800 , though a standard fitting for the British market. These radial-bly tyres , hand-finished and considerably more expensive than mass production tyres, had been developed by Pirelli and Porsche engineers at Weissach on Porsches unique 4.5-metre drum, on which the tyres can be run inside the perimeter rather than on top of a rolling road surface. Its construction resembling that of a racing tyre, the P7 was the last word in road tyre equipment and truly matched the capabilities of the Porsche Turbo. The wheel diameter remained at 15 in and a new speedometer had to be fitted to compensate for the 50 percent tyre profile."

So , since 7 & 8 inch wheels were standard on a 1976 930 , the 50 series option (at DM 800) obviously could not include the wheels. That is the basically what the reference above says - this option did not include wheels. At least in 1976MY for a 930....and in 1977MY ...I do not think there was a 15 inch 50 series tire option , I do not have a 1977 MY option list or price guide listing options.

Echoing the Cotton reference , again is the price list . It clearly shows this is applicable to that year C3 also . And as stated prior : m493 & m401 , the two 7 & 8 in. wheel options (black center & anodised center) , both are specifically notated as coming with 60 & 70 series tires. The m395 text description states only : "Reifen".

Also echoing the M. Cotton reference is the 1976 US sales brochure which lists the 1976MY 930 with 70 series front & 60 series rear tires as standard fitment.....with any option concerning P7's (m395) on a 930 , wheels are redundant. There is no P7 series tire option specifically for a C3 vs. a 930 - only one.


I'm only going off multiple sources of evidence / documentation , that I have access to. I do not believe it is all incorrect , just too many references. I researched the 1976 m395 option some years ago , that is why I am farmiliar with it. It was also available to be fitted on a 1976 2.7 Carrera with yet another distiinct speedo calibrated for 50 series tires .....a mechanical unit.


If you want to call trying to be accurate nitpicking , then fine by me .

Perhaps I can clear this one up with the following spec I obtained from the factory for the owner of a 1976 Carrera 3:

engine 666XXXX
gearbox 165XXX
color B2=continental orange
interior 36=leatherette brownbeige,seats leather,seatinlays Tweed
delivered to HG=HongKong
options U56 (groupnumber contains 058=shock absorbing bumbers, 197=stronger battery, 474=Bilstein-dampers,
568=colored windows, 650=sliding roof) and 395=tires front 205/50 15,rear 225/50 15, 399=colling system,
401=forged alloy wheels front 7x15,rear 8x15, 441=electric antenna, 462="Carrera"-script black, 481=5-speed gearbox

As can be seen there are the two options of 7&8x15 Fuchs M401 and the low profile tyres M395.

However just to confuse matters for the 1977 model year M395 became 6&7x16 Fuchs with low profile tyres as fitted to the UK 'sport' model.

Bill that is a beautiful car there. Make sure to get it registered on the Carrera 3.0 registry which I run: Porsche 911 Carrera 3.0

Colly,

You've already got it registered at #156. Do I see your Targa for sale by the way.

Guy

Carrera 3.0 Registry
 

Colly,

I have emailed you a couple of times to update my cars listing #156 to show it's new ownership & address in Australia plus a few more details about this car.

Please PM me if your not receiving these.

cheers
Bill

Great info !

I checked my speedo and it looks like my car came with the low profile 15", it has the "501" number.

Hi everybody, can some of you clarify why the 1976 300 kph speedometer was reverted to the 250 kph type in 1977?
Thanks a lot. Max

New Arrival to my Collection :)

It's been repainted in lime green and set up for track use.

mine is '76 C3 Targa 299, w/ option 474, 395, 401, 441, 462, 481, 409, 220, 261, 454

The tire seection changed from '76 to 77
for a C3 in '76
base wheel/ire was 6 & 7 x15 Fuch w/185/70 &215/60 tires
opt1 was 7 & 8 x15 Fuchs w/ the same tires
opt2 was 205/50 & 225/50 on the 7 & 8 x15s

for '77 C3
base was still 6 & 7 x15 Fuch w/185/70 &215/60 tires
opt1 was still 7 & 8 x15 Fuchs w/ the same tires
opt2 was 6 & 7 x16 w 205/55 & 225/50 tires

the UK Sport model was just that, the English importer spec'd it for their market, no one else(except possibly some other importers, Italy comes to mind) had that option

The US importer never had the option to import a C3, they all came over privately. But when the did the spec'd them w/ things like AC and sunroofs, rarely wider wheel or tires or even lsd
