Welcome to Club Lexus.
Wheel fitment is how much are you willing to spend to make more aggressive wheels fit the body. On conservative fitments this is less an issue and it also relates to how low you want the car to sit when driving and parking height. If you are after that flush fitment when parking it is going to be poking while driving. You can be flush while driving.
We've discussed wheels on many cars and there are some current threads to reference. In a search use "wheel fitment".
