All depends on how you value stance, ride quality, and price. I run 225/45/R17 Pirelli P Zeros on 17x8.5 Momo wheels and I have found it to be a good blend of all 3. I am on stock suspension as well at the moment so there is definitely still a gap between the fender and wheel, but am planning to drop the car only about 1.4", which will clean up the stance but still allow the car to be comfortable/maneuverable.
There are a bunch of old threads on here from people who have much more insight than I do, so be sure to check them out.
