I haven't heard anything about that particular brand, but they look pretty cool. You might want to find out the weight and offset of each wheel before you purchase them. The only other thing I might be concerned about is all those tiny little silver/chrome rivet-looking things around the outsides of each wheel... they're gonna be a pain to keep clean (if you obsess about that kind of stuff like some people do).
About the lug nuts - no clue.
