Here's what it looks like when I had 18x8.5 et 35 front and 18x9.5et 22 rear, which is the perfect and correct fitment for this car. Tires are 225/45R18 and 255/40R18 Advan AD08, which run quite a bit wider than their sizes suggest. For less aggressive tires, you could probably get away with a 245/275 setup.
I think the offsets you listed are a little low, and the fitment is more aggressive than what would be ideal for perfectly fitting in the wheel wells.
