Scott!!!
It dragged because either you mounted it wrong, or you did a little too much agricultural racing...
The unit is held on with 4 Zeus fasteners, how simple can that be...
The only time I lost one is skipping through a gravel or dirt trap. Keep it on the track, remount it correctly or replace the belly pan if you bent it up. The pan can be replaced with a drill and some pop rivits.
The unit is suppose to follow the plane of the lower valance and extend back to smooth the air below the car, while the splitter lip creates downforce.
