a 205/45-17 tire is like a Civic tire... they are way too small, and if you use that tire your wheel gap will look huge. Get a 215/45-17 tire, they look much better.
On a black car I would never put gunmetal rims (I'd personally never buy gunmetal like rims) That'd be too much black. I think something with a silver finish would be better.
Wheelmax is alright... just the people that work there are assholes and their customer service SUCKS!! (personal experience)
I highly recomend
www.tires.com... their people are more friendly, they have free shipping, free lugs, free mounting/balancing... where wheel max charges up the ass for all that crap.
