Learn how to avoid major bumps and how to slow down for speed bumps. My car is lowered 2.5" front and 2" rear and the only scraping issues I have are speed bumps if I don't take them right, and my driveway. But I just scrape the chin spoiler slightly on the droveway. My exhaust rarely scrapes unless there's a sharp speed bump that I can't take at a good angle.
