I have now dissabled the drivers seat, not much to say since a picture says more then 100 words.  At least it gives you a hint of wats waiting you if you try it yourself. 
I started with stiffening up the seat springs by using a plasted wire and it works very well.
Still it's quite soft at he front of the seat so I've used a pice from a "Foam Mat", the "Foam Mat roll" are kept in place by a wire so it stays where it should. small things but they really makes a difference.
