Default 17 x 8 cup wheel question

I have recently acquired a couple sets of the factory Cup style wheels. In looking at the wheels I have two different part numbers for the 8" wheels. One part number is 965.362.126.00 and the other is 965.362.126.01. Both part numbers are 17 x 8 wheels with 52mm offset and look to have been made in 1992. The front of the wheel looks the same but when looking at the back side the wheel construction is totally different. Does anyone know by the part numbers what these originally fit? Is one design preferable to the other (lighter, stronger etc)?


Thanks

john

Dear John,
One was for the 964 and the other for the 968.

968 wheels in the optional 17" size were 7.5" front and 9" rear. The only 8" fronts came on the Turbo S/RS cars, and they were 18" Speedline 3.6 Turbo types, IIRC.

Dear Damian,
I think you need to read the original post again. John does not mention front or rear wheels. He just mentions a size.
8JX17 wheels were optional for all 964s (from MY 1991 onwards) for the rear.
You could also get 17X8 rear wheels for the 968 and one of these part numbers just happens to be allocated to the 968. Maybe not in the USA I have never cared to look but certainly over here and they were scooped out at the rear.
You should really read these posts more carefully before responding. By the way you could have any wheels you wanted fitted to a NA 964 or 968 as long as they were not 18 inches and you asked.
Ciao,
Adrian

Adrian, does this mean that "any wheels you wanted" were then considered factory options and would identified on the options tags in the trunk and the manual?

Thankx, J

Adrian, my minister gave a nice sermon today, I don't need one from you as well. Anyway, I mentioned the 8" fronts only because that's the only time I've ever seen that width on a 968 wheel. I'm going to cross post this on 968.net and ask if anyone there owns a 8x17 factory wheel, or knows of its existence. I've personally seen over 100 different 968's, and none have a 8x17" wheel. While US and RoW cars have some differences, the wheel size choice was the same in all markets. I guess it's possible John's wheels were custom ordered for a 968, but stock/optional 968 wheel choices were 7 & 8 x 16, or 7.5 & 9 x 17.

Dear Damian,
I do not care what anyone has seen or thinks they have seen, I used the Porsche internal wheels catalogue. Sadly I had to return it after my book was finished.

Dear Joe,
The answer is yes. If it was legal you could have it. 928, 944, 964, 965, special custom wheels. Some people did and there were some kool one off wheel sets made. If your pockets were deep enough.
There was a special set of 17 inch wheels made just for 968 Turbo S/RS and RS 3.8 owners. You will not find their part number in any brochure, or standard parts catalogue but you will find them in the "for customer only" personal manuals. I have a friend who has both these autos and a copy of this manual.

Ciao,
Adrian

Adrian, from YOUR own "Wheels and Tires for the 964 Series" spreadsheet you list both 965 362 126 00 and 965 362 126 01 in 8 x 17" with 52 offset as 964 wheels. Saw it with my own eyes! And you mention there were 'subtle differences between 964, 964Turbo, and 968' versions of the wheels I would imagine they would have different part numbers, leading me to say the two wheels are simply ONLY 964 wheels, and not for a 968.

Greetings,

I have the .01 wheel fitted to my RSA for what it is worth.

Best,

Don

Dear Damian,
Yes this is correct and because I have not written a book about the 968 I did not go into further details. Well actually I did but it was taken out.
Your assumption about changing the part number is incorrect. For the 968 they were scooped out at the rear. I will not go into the Porsche policy of changing part numbers but let us say this is explained in my book with some examples which clearly identify how Porsche do this.
Porsche issue a document called the Räader und Reifendimensionen every now and again. This is an approved document by the TÜV. I have the latest one for the 964. In these documents which update the original data which for instance I used for my book, you learn these things. Unfortunately for me I did not know of the existence of such documents until I ran into a problem with the 9JX17 wheels on my C4 and the local authorities. I then discovered that for quite some time that the 9JX17 wheel has been approved for all NA model years of 964s. This now means that the statement Porsche only approved 8JX17 for the rear of a 964 is no longer correct. You can install 9JX17s legally.
Now back to the 8JX17s. This size is also known as the winter wheel size. ALL Porsches which have a 9JX17 approved for the rear also have approval to use the 8JX17 in winter. Why? Because you cannot use snow chains on a 9JX17 wheel.
Data is being updated all the time. Even some of my stuff is out of date. This forum provides the most up to date data in this area. Plus of course as I go along I find out about these documents. They used to be issued as Technical Service Bulletins and I am sure you will find the 1995 series quite useful.
To summarise. Our owners manuals are out of date. The technical service bulletins I used for my book in the are of wheels is out of date. The parts catalogue is out of date. There are other documents such as the one I mentioned which is sitting right in front of me now. I also received a document on springs for the 964. Way different from the part catalogue. Contains part numbers not in the parts catalogue. All this stuff will go into the second edition of my book when it is decided to do it.
Ciao,
Adrian

PS: This whole series of certification documention only came to be in my possession because I had trouble with the wheels and springs on my C4 from the Swiss authorities. The past two months have revealed a whole new world of documention which makes a lot of things previously thought redundant.
