Wide wheel and tire combo in 17" or 18"

I am planning on getting my wife a set of black and polished bullet wheels for Christmas to replace her silver 17" bullets on her vapor silver '08 GT and want to replace them with an aggressive looking set of wheels and tires. I like 17" wheels for accelleration purposes but 18" would be fine. I am not interested in 20" or any of the bling bling looking wheels (no offense). What wheel AND tire combination (in the black and polished bullet design) looks really agressive? I want the wheel tire combo to really give it a really nice agressive look without rubbing problems and without too much difference in the overall diameter of the wheels so her 3.55 axle still works well to give good acceleration. Her tires now are 235 55 17s. Pictures would be great!! I would even like to see pictures of wide and aggressive bullet wheels and tire combinations even if they are not black/polished. Thanks!!

Thanks for the initial input folks. Casey4s, That looks sweet. I checked diameters and it looks like 555s in 255/45/18 up front and 285/40/18 in the rear may be the ticket. Anybody have some rear view photos as well to show the aggressiveness of the width?
I agree there are some 20" wheels that are not too blingy but with those small sidewalls there are ride issues and really significant drag racing issues as a result of the small sidewalls. My wife wouldn't accept the rougher ride and I don't want to lose any of the 60' performance. Thanks for the comments though.
More photos please...

thanks Kool! How did that taller rear tire affect your accelleration? I imagine you felt a little loss but I guess that would depend on your starting ratio as to how much you might feel it.
