dont know if this is the best way to explain it, but if you look under your car from the front, look at the way the front bumper molding looks under the front of the car.
This was the only clearance issues that I had when the molding continues under the car it starts to curve towards the ground where it ends. When I lowered it, going over speed bumps that would scratch. If I were you, I would find some way to either cut it so that it does not go down to such a dip or you will ding it up quite a bit. I was always afraid that the bumper would rip off one day. Just take it easy over large speed bumps.
