Re: pic: My First Sheet Metal FRC Drivetrain
As you mentioned, the double-cutout is going to result in a lot of twisting between your two drive pods.
A couple of things you can (and should) do to mitigate this, without any extra systems. First, there's no reason for your cross members to be so close together. You'll get much more rigidity if you move them to the extremes of the bellypan.
Second, your cross members are only supported on a single flange. They will have a tendency to bend about this flange. You can add a whole lot of strength by modifying the cross member's flange so that it rivets to the top flange of the drive rail.
