Well, I got my new rims on today. They're the Niche Venice.
I ended up getting 18 x 8.5 114.3x5 with 45mm offset. I was a bit nervous as Ody can testify to and I did put the aluminum hubcentric rings on (72.62 x 70.3mm) .
I'll get pictures up when the weather is better and I can wash the car.
No vibration, no rub at all so far. I did 3 or 4 tight radius turns at the shop and also drove 35 miles on them so far and checked for any rub (due to the 45mm offset) when I got home.
Got the car up to about 90mph on the highway and noticed no vibration at all and alignment seemed straight as an arrow.
Tires are 245/45/18 Federal SS595

I'm hoping to have photos in the next day or so of them on the car.
