NICE WHEELS!!! Your Civ looks nice mate. As far as ideas, have you considered lowering? I think with the setup that you have it will look awesome!!! Maybe a Carbon Fiber hood? They look good on that color.
Have you thought about the Honda Grand Prix Kit, it looks great on Alabaster Silver. Or there is also the Mugen Aero parts (splitters, wing, fenders). I don't know how easy this stuff is to get hold of down under but it gives you something to think about.
Lowering also improves the appearance and it's definitely going to be one of my next mods. Have a look through the modification projects part of the forum and it will be sure to give you some ideas
