Hi Aaron, I'm just thinking aloud...

Maybe a motor plate made from iron, or just T6 rear A-arms could do the trick, or aluminium wing mount, you can also go for an aluminium rear shock tower. Going a little crazy you can even think about a machined gearbox. All these things are heavier and place more weight at the back.

I believe that a 4mm thick chassis could also help on a car so light.

I'm aware that some of the ideas beside moving CG further back (and adding weight) will also rise CG and that have to been considered and tested.

I really love these desing and believe that with some mods you could use Ni-Mh cells, with minimum legal weight and perfect CG.
