Rim advice please

Hey guys i need some advice. Im buying new rims for my altima (its a white se) and was planning to go with a set of 18" RH c2 on ebay then i stumbled across a set of gunmetal rims by a company unknown to me and i thought that the rims would look great on my car.

My question is should i stay away from these kind of rims or has someone hear good things about them? Do 18" wheels create problems on 2nd gen altimas? What should i do?

I would check their feedback and see what the other buyers have to say. I think they'd look pretty good on your ride.
