Any pics of the inside, particularly of the mounts you made?
The tips where they bolt to the fenders are just factory style, which is just a hole for a bolt to go through. Since this is glass instead of plastic, I have a rubber grommet between the fender and the bumper, and then a bolt and nut. As for the bottom, this is where most of my support is. The pic below is my aluminum frame for my belly pan, and the front beam also supports my front bumper. I will show that next. This frame is mounted solidly to the chassis.



Here, you can see my support beams, linking the bumper to the belly pan frame.



Now the frame has been skinned, and the belly pan is flush with the custom bumper that is 3 inches lower than stock. When I put weight on wheels, the control arms settle just above the belly pan. The bumper mounting and the bottom underlay are all integrated as one system.



This set up sits pretty low, but really reduces aerodynamic drag. I do take this EV up to 100 mph, so I can really notice a difference at high speeds.

You can see the difference in how low it is compared to the metro in the foreground.
