the awesome-gti golf has azev a's (correct me if im wrong) are they 17s or 18s?

Always liked the older style rims like these and borbet A's. Look
on mk4s
i want some, but dont want to get the size wrong, will i be able to pull off 17s? the photo looks like 18s?
I thought they looked a bit small ^^^
You can always drop it more if it doesnt look right lol.
An inch is alot to some people though
