I have nearly identical track alignments on both cars and have no issue with obtaining the camber I need. Both front tracks appear to be the same. When I measured the longs albeit not as i would have liked I found that the axis for the A arm was changed and that it isn't a straight forward outward or inward change but pushed the caster forward using the 993 longs on another car I did. That was a wide body. Both C2's use upper mono ball plates. I have no actual measurements but visually I can see no difference and both cars align without issue.
For some reason I can't post pics today but both show to sit nearly identically. I will try to measure but too busy for this right now. I will report back when I get a chance.

I was having trouble with the site too - seems better now.
I get it - and I'm sure there could be some other variables, too. The one undeniable thing is - where the balljoint goes in the 993 upright is different than the 964..and this is relative to the face of the upright (4 bolt face). So no matter what, using a 993 upright on a 964 (and keeping 964 longs) pulls the wheel in 8mm (or close to that). Put 964 and 993 uprights face down on a table with no hubs and you will see what I mean. Strut mounts, drop links line up perfectly between the two...the balljoint location, not at all.
Of course, different wheels, spacers, camber plates, ride height, rolling fenders...all affect how you experience this but with everything being equal, the front track width is reduced by about 16mm total by changing nothing but the uprights to 993.
