I have a technical article written and archived on Rennlist that lists all Fuchs suitable for 911 use, including offsets, backspacing and Porsche part numbers. I also identify further information sources.
For the life of me...I can't seem to cut and paste to repost here !
Look at Rennlist archives...

Wil-

I found it- see if this works (I know the columns won't line up):

Listers:
Since my last post on this topic, in answering Sami Dakhlia, I went through my own files, and these were complemented by later posts from Mike Piera, Bill Verburg, and John Haley. Combining all sources of info, and noting that there are 25.4 mm for one inch, we get:
model size part number offset backspace
944Turbo 16x8 951.362.117.00 23mm 125mm
944Turbo 16x7 951.362.115.00 23 112
911 16x7 911.362.115.00 (early) 23 112, 911.361.020.44 ( late) 23 112
911 16x8 911.362.117.00(early?) 10.6 112, 911.361.020.45 (late?)
911 16x6 911.362.113.00 (early) 36 112, 911.361.020.43 ( late) 36 112
930 16x9 911.362.119.00 15 130
More information on these ( and other ) Porsche wheels can be found in the following reference sources:
- Porsche Panorama, Sept 1996, p.27
- Porsche Panorama, Dec 1989
- Upfixin der Porsche, Vol 8, p.179
- Porsche Panorama, April 1995,
- Excellence , June 1995, p.107 by Jim Pasha
- 911 Performace Handbook , Anderson 2nd ed, p.215
Most of these papers were authored by either Bruce Anderson, or Jim Pasha, both with excellent credentials. Nonetheless, there are errors in both lists, mainly simple errors in transposing model numbers ( Anderson), or mixing up of 7" and 8" wheel data (Pasha). The backspace column of the chart in the Sept '96 issue of Pano seems to uniformly overstate the backspace by 0.35 " for all cases ( strange...). I *believe* the above list above is correct, but if I'm not, I'll be in good company . Hope this helps clear
up some confusion on this topic.
---------------------

It looks like you didn't include 15" wheels, though, Wil, only 16s. It should be noted that in answer to the original question, there is one 7" Fuchs wheel that does not have the 23mm offset, and that is the 7x15" 911R wheel, which has a 49mm offset, I believe, to fit the rear of an early narrow body 911 with 225 tires on it. You aren't likely to find many of these, though, as the supply/demand ratio is very low.
