Now for the wieghts.

The spare wheel well is over 5kgs by itself. Obviously not all of this is going to be savings, as I will still need to fabricate a floor panel for it. But its something, and all adds up with the other savings.

The OEM fuel tank, and associated parts (mounting hardware, fill tube, charcoal cannister, pump etc) is 22kgs. Which is significant. Even after adding the FCST, pumps, and fabricating mounting hardware. The new set up will probably come out less than half what it replaces. And have more pumps, better anti-surge and more crash safety.

I also chopped the ribs from the rear of the wagon roof out. These things are quite pathetic. I think they are more suited to hold the roof lining up, than brace the actual roof. For one, the roof sheet metal is thicker than the braces sheet metal. And the braces dont actually even attach to the roof. Instead they have about 10 blobs of a setting foam, that is sandwhiched betwen the roof and the brace. The foam isnt really even adhesive. Its more of a cushion to prevent physical contact. So i dont really have any issue removing these bits. Plus its all rear of the cockpit anyways. Doing this free'd up almost another 2kgs. (Aswell as the other 3 to 4kgs i free'd up from removing the sound deadener sheet metal stuff I mentioned earlier.)
