There were actually two layouts for the Acropolis WRC SSS.
The 2006 layout can be found here:

linky3
The 2005 layout was a bit simpler, but still fun:

The 2006 layout was supposed to make it more interesting by keeping the two cars in parallel for more time.
For what it's worth, I was at the 2005 SSS, it was great atmosphere. In 2006, the "organizers" saw that there were a lot of people interested in this "rally stuff" and they wanted to make more money out of it. So they decided to beef up the ticket price (from 20 to 30 euros), organize _two_ super-specials, on Thursday and on Sunday, and that's why in 2006 the stadium was pretty much empty both times...
