I figured this would be of interest and I was sitting around on Facebook today and saw a post by StreetSweeper.NW and it was about an application for iPhone and Android called Slammed Navigator.
Apparently it's still being worked on but here's a description from their site:
"Slammed Navigator was thought up and built by a group of import car enthusiasts in the Seattle, WA area." - Slammed Navigator
"Slammed Navigator is a navigation application specifically built for lowered vehicles who have difficulty getting from place to place while avoiding potholes, uneven roads, bumps and more."
Best part is it's going to be free; "We will never charge you a penny to use Slammed Navigator, nor will we ever bombard the application with annoying advertisements."

I'm looking forward to the release of it
