Which wheels will fit which cars?

I have a Superb, and am looking for some new wheels. I have just found out that there is a 100mm 5 stud wheel and a 112mm 5 stud wheel, which one have i got, any idea?

What other wheels from which vehicles fit, Passat, Touran, A4, A6, A8?

5x112 - new Jetta, new A3, Passatt current and previous version. Think A4 too, not sure about A6/A8.

All from memory so hopefully reasonable accurate

The Audi A4 is 5*112 as well, as I found when I picked up some wheels.....

New Octy is that pattern as well.
