How much weight will side skirts, a new hood, neon lights, and a spoiler add to my car? How much will it all cost? Will it effect fuel economy? What happens if i hit a bump with my car being real low? Will adding all this void my warranty? Will all this add or subtract from my resale value down the road? Any other accessories that would make my car look nicer and less girly? any other details that will be helpful?
