lanner has an article on his page about wheel fitment too. here's a thread you should read for sure:

on my car i'm running the complete stock 944 setup, including the shocks. the rear of the 944 is similar enough that you could run pretty much anything built for the 944 on your rear, including koni adjustables and presumably coilover conversions. the front is a different story, but the rear is easy. i lowered my car by adjusting the spring plates, but i did it too much and it'll have to go back up until i can get fenders.
there are coilover conversions from blind chicken racing, plus other places.
and yeah, to my knowledge all porsches come with the 5x130 pcd, which does narrow the choices to factory wheels and high dollar custom ones.
i have pictures of my car, but they might not be helpful as it's being built slowly over time, and not with cool build-up pictures. my avatar is my car, but i can show you others if you're wanting to see them.
