Starting to customize ragtop Z

It's not my car, but my dad is wanting me to help him decide on some mild mods for his 05' 350z convertible. It's black/black. He just bought these wheels:
Ebay item #: 230151338154

Tell me how you think they will look on it. He also wants to buy a rear lip spoiler.

What are the best performance mods for this car, while still letting it be daily driven friendly?

I'd start off with small things. a lot of the mods for these 350z are expensive, but i'd get these three things if i were you. Cold air intake, catback exhaust, and i'd get a reflash from technsquare or another reputable reflash company. 350z tend to run lean with modification because the ecu over compinsates for the mods resulting in loss of power from mods or barley any gains. So it's crushal that you get a reflash along with any mods you perform. Or if he doesn't really plan on modding it much he could just go with a reflash.
