Hi guys ,

I was wondering if the Cup 2 wheels were ever available as a factory option for the 964 series . Or was this the standard wheel for the 993's .

Thanks in advance,

No they where not. Cup 2 were for 993's

They're lighter than Cup 1s.

that's what I thought as well however after some research I discovered that Cup 2's were offered on late MY's 964s during the switch over to the 993. perhaps someone here has a 964 window sticker that backs that up.

Cup II's were first used on the 1994 928GTS. There were a few 993's delivered in 1994 with the Cup II's. All of the 964 C4 widebody cars came with Cup I's in 7&9 and they only made 160 1994 C2's of the ones i have seen they had CupI's in 7&8. Since the 964 production ended in early 93 I kind of doubt that the CupII's were optional. The 1994 sellers guide and the Technik information does not make any mention of CupII' wheels offered.

It might be possible that they came on some ROW 94 964's but I doubt it. FYI Cup II's were optional on the 1994 968 with the M030 package and came with the CupI's on the 1993 MY M030 968.

They are lighter by .6 pounds 7" front and 3.6 pounds 9" rear. IIRC they are made by SM vs speedline and seem to be far less desirable than the Cup I's currently.

PS: It might be that what you are referring to is that Porsche approved the use of the 993 CupII also know as the design 93 wheels on the 964 but I do not believe cars were delivered with them. They were very specific back then that the 18" wheels offered on the turbo and 3.8RS were not to be used on a 964 but we have all been doing it for years without any impact.

Thanks guys for the replies.

From '93 all 968 Sport and Club Sport had Cup 2's. While slightly different offsets, they would have worked for the 964's too.

Interesting. We did not get the CS here but all references I know of to 1993 CS show them wearing CupI's. Here is an example. Would like to know more if you have additional info on that.

If you reference Adrian Streather Enthusiast Companion for 964's, pages 279 (text), 281 (chart) and 288 (picture), they all reference the "Cup design 93" wheel which is the Cup 2 wheel.

Interesting. Very often during a model switchover and year overlap, new model accessories or options are, or were, added to the outgoing model to shift remaining stock out from the dealer showrooms and dwindling factory lots.

You're right Anthony, early '93 S and CS 968 started life out with 17" Cup 1's. These were also offered as options for the standrad 968 (up from the 16" Cup 1's). The introduction of the 993 end of '93 saw the Cup 2's which made their way as 968 options - #398 - '17" 993 look wheels'. From year model '94 onwards the Cup 2 was standard for the S and CS.

I won't say the info is wrong however. There are a lot of things Adrian referenced and noted that as time has gone by we have learned were shall we say less than accurate. He also mentions a 17" modular Speedline wheel for the 3.8RS only. These have never surfaced in the 15+ years I have been gathering info on these cars. I have all the factory order forms for the 3.8RS and RSR. I know a couple of owners past and present and they are not aware of such a wheel being offered. There is no mention of any wheels offered other than the 9 & 11 x 18" for the RS and the 9.5 & 11 x 18 for the RS/RSR with center lock option. So I am assuming some of his info is inaccurate. Adrian referenced a lot of info that was for not only the 964 but the 993, 928 and 968 in his book for the 964 so I have to discount some references.

This seems to eliminate a lot of the non pertinent info regarding these cars. As you can see there is only a single reference to the 17" wheels as option code 403.

https://www.stuttcars.com/technical/...des/964-91-94/

All of the factory ordering information I have for the 94 964 shows only one option 403 for the design 92 or Cup I in 7 & 8" x 17 sizes. There is no reference for the Design 92 or Design 93 just a 17" wheel. The picture on page 288 of Adrian's book shows an RSA with design 93 wheels but states it is an "approved combination". We know Porsche did approve these after the fact. I would think someone on the RSA registry would have made note of such a rare example by now. Also all the ordering info from PCNA shows the RSA to be fitted with Turbo Style wheels without reference to any other wheel option.

We currently have a very early production low mileage 94 993 in my friends shop. It was one of the first to enter the US. The production dates on his design 93's are 10-93. Any wheel fitted to a 964 would have had to have been made long before this date to make it onto a 964 for US delivery.

So although there is a slim possibility that the design 93 made it onto a 964 from the factory my research leads me to be more than skeptical.


I was speaking to a friend last night who has a 94 968 with factory 17" wheel option. He is not the original owner but does have all the original paperwork. It is a low mileage very clean example yet it is wearing CupI's. He believes they are original based on production dates and finish and is interested in finding out more. Interestingly the info provided for sales by PCNA states only Turbo style wheels as an option for these cars. It is possible the design 93 was only a ROW option on the 968, S and CS which we did not receive here. Interestingly the PCNA info references 398 as left outside mirror so I am not sure how a salesman would know how to option the design 93's.


It would be interesting to see if any 964's were fitted but I would be shocked if they were or if it can be proved.

So if anyone has some objective evidence to a 964 coming from the factory wearing design 93 (cup II) wheels I would be very interested to see it. Until then I have to assume as with most everything else I have researched that it did not occur.

Wondering if, that while maybe not an 'official' wheel option for the 964, some buyers of left over 964 prouction managed to swing a dealer sweetener to throw in a re-boot with a set of Cup 2's instead of the standard Cup 1's. This then may give rise to claims that some 964's were delivered with Cup 2's. Often I've done some bartering with dealers in the past to add other range options available at the time.
