Here's my opinions, as if they are important.
1. Since you already have it and I cant force your hand on the potential riceyness of a highboy spoiler on an FWD, let's look at it this way. I think your wing may work nice with an SVT body kit, but how about this for a spin on originality? Do like bnoon suggested and put the wing on 2 or three inch pedestals instead of 8" or whatever it is now....also, paint the WING body color, but powdercoat the PEDESTALS/MOUNTS the same color as your wheels, whatever you end up going with.
2. SVT body kit with mirko splitter is about as agressive a body treatment as is available...would definitely balance out the car.
3. Exhaust looks fine, but having an SVT rear valence back there would let you see all you want to see but hide what you want to hide...accentuate the exhaust without overstating it...right now the arse end looks sorta nekkid.
4. Consider painting the chrome trim ring body color. Also, consider changing your decal color to match your wheel color.
5. I, for one, love gold/bronze wheels. I think a dark gold wheel would look smooth, but only if you carry that same color to other trim elements (wing pedestals, decals). Too bad they dont make Volk Racing TE-37's for our cars...that dark color gold and spoke pattern would be the **** with your midnight blue color.
That is all. You'll probably get a thousand different responses.
