Our ultimate goal is to mount our heaviest parts on the bottom of
the car. This includes the two motors, the differentials, and 180
batteries. To do this, we decide to cut out the existing car bottom
and replace it with a flat bottom. Bracing will hold the diffs and
motors. An interior floor will mount over this to separate the batteries
from the driver's compartment.
We have to plan carefully, so that this massive cutting and rewelding
leaves the car body stronger and stiffer than when we started without
adding too much weight.
