I love sharing shat I have done to cars...hope this helps those who aren't sure what to do. As I said above I used carbon fiber to build my box. This was a 1000mm x 1000mm x 5mm sheet made of a single layer of carbon then a layer of special ridgit foam than another layer of carbon. The sheet wasn't cheap but carbon isn't, but dam it looks cool Some of these pics have captions which I had used on my old site.
1. This is the original cardboard template I made to get the shape of the side wall, making sure there was room for hoses and fmic pipes.
2. Here it is in place, I actually made a second one that was neater and had straight edges .
3. Next was the top, again made in thick cardboard.
4. Here it is in place.
5. Adding more cardboard and taping it together to make the entire top.
6. Not sure about excited...broke more like it
