Tire rack had a couple that fit the Fiat 500X - 5 on 98 and acceptable ET. The hub bore is a bit small - you could probably grind/sand them by hand to make it fit. I made up a 1/4" spacer and use them as lug centric versus hub centric. 16X7.5 if I remember correctly.
I posted a thread on them when I mounted them up last fall. You can search on my name and find it. I mention tire sizing as well because that is important too. and they were $800 ish for the set including tires.
84 Spider - Long gone, but started the addiction; 85 GTV6 - Current project, Supercharged, Mega Squirt; 88 Verde - "Milo" It has a name, must be a keeper
