What would be great is to get some silver wheels to match your graphics. A body kit would really complete the car's profile....would bring it all together so it wouldn't look quite so bolted on.
The big wind is debatable, but I honestly haven't seen a 4 door car with a good looking spoiler other than the factory spoiler. But, if you want to keep the wing, a chin spoiler from Mirko would balance out the car. And I think the car would look better without the blackouts....especially if you did clear corners or something.
