Having estimated the weight of the car, I have decided that adding lightness is top priority! To achieve this I can either remove things, use exotic materials, or drill holes in things. Now removing things is not really doable as everything is really needed, I think. Using exotic materials, read carbon, is far too expensive, although a very good solution. That leaves me with drilling holes, its cheap, easy and pretty effective!
So the first thing that caught my attention was the pneumatic pump and accumulator plate.
