I like the 17s but I think the 18s fit the well better. They come out further too and are more flush with the body. I would change to a taller side wall tire though. This was a problem I was concerned about with my TA when sizing tires. I wanted the bigger rim but wanted a meatier more muscular tire. So I went with 40 series tires. I have 245s front and 275s rear. Here's a picture of my car. It's not the best but hopefully it shows another option.
