It appears that I hit the metal plate on the underside of my car so hard that I punched the botl through the frame, and bent a metal tie between the front sub frame and the main body.
This is the back right of the mid plate. It is pushed up and at a weird angle.
A long view of the mid plate, showing the damage. The far bolt is the one pushed through the frame.
You can sort of see that the strap here has taken some damage. This is where the rear of the mid plate attaches.
Also, it's important to chock your wheels, so the car doesn't roll while you are underneath it!
Some other random pictures, I'm tired of captioning them.
