It does seem to make a lot of sense and 20kg is a useful weight saving from the front of the car and quite high up. I can save another 20kg by matching the boot lid to my carbon bonnet., I don't have rear seats so it kind of helps make up for the 4wd system and small roll cage.

The pug 205 is only 870 kerb weight in standard form so if I can get close to 1000 /1100 kg I will be happy. I think a Saph 4x4 is about 1280kg?
