IIRC, on the C4S (at least mine) is came with Techno rimns with 55 backspacing. The original owner did not order the factory spacer option. I want to say it is option code EKN with 5mm spacers for the front and 17mm spacers on the rear, I could be wrong and am syre somebody will correct me of so.

Measure what you have. Look on eBay. You want a 14x1.5 thread, 19mm head, ball seat w/washer. Shank length is what you want to know (the threaded portion plus mm or so before the seat).
Looks like 45 or 47mm with the above. Slightly longer won't hurt anything.

Within reason...
Cautionary tale, not from a 996, but something I pay attention to on every car now: I was experimenting with wheel spacers and longer lug bolts on another car (Audi S4) and I had an interference issue behind the hub that was causing binding and preventing free rotation. Again, it wasn't a 996, but I'd urge you to double check any longer lug bolts for interference with stuff behind the hub.

I found the bolt with help from people over at Pelican Parts:

What a PIA...
Sigh.

Porsche measures from the bottom of the threads to the bottom of the bolt head. So while the 'showing' threaded part of the bolt is 45, the bolt length seems to be about 63.

Ok, but how do you know the bolts your getting are measured with or without the spacer. I have bought quite a few Porsche specific bolts and they were always measured on the below the spacer length.

The corresponding 63 mm bolt matches the Porsche Ball Seat in the diagram.
And if you look at the picture of my existing bolt, I would say the entire shaft length is probably 63 mm (45 showing).
Worst case, I send it back for another size.
