I have been working on a box cavity extension for the CR-Z.
I am happy with the overall result. It is made of cardboard, hot glue, tape and plastic bags to protect the cardboard.
This is a proof of concept and will undergo some tweaks before I attempt to fibreglass and colour match it. Still thinking about integrating some sort of rear diffuser.
Let me know what you think. I am open to suggestions.
Cheers !
