I plan on re-painting my 86 RX-7 (its stock charcoal gray right now, but looks like h*ll) I was thinking a metallic black (I read Obsidian Black for Mercedes?) or go with a cooler deeper metallic charcoal. What do you guys think?

I also plan on putting a ground FX kit and a bigger spoiler than my factory sports spoiler, any suggestions on an aggressive looking kit and spoiler? (I already have 15" 5 star rims they look worlds better than stock, but still not the aggressive look I'm going for, so I'm open to pretty much all suggestions)
