Whatis the cost on the tires? Be interested to keep an eye on your impressions for future replacement of the 18s on my GTI. Hancook has been getting some pretty good reviews on their HIPO tires latley. Well priced 18s are gold.
The wheels? If you are happy then I'm happy for you. My personal preferance is that I don't like bronze/gold wheels on balck cars. Its always struck me as a SUBARU STI thing and doesn't work for me personally on upscale looking cars like the Lexus. Multispoke rims? Not thanks.
Prefer something like this

Wheel gap isn't that bad. I've seen way worse. Closing up the gap a bit isn't worth the ride trade off when you have potholes (I know all about that) Ever thought about getting a set of clear or smoked turn signal lights? Very inexpensive and getting rid of that orange on the otherwise balck car would make nice difference.
