Hi M8,
I went to check the alignment today and the guy suggested me to try an open alignment ( 0.6 per side ) only on the front wheels, and so he went ahead...
this afternoon i had a run on a mountain road to try it but...a real s..t: the car was understeering when pulling hard in corners
the opposite of what i thought) i'd come back to my original idea ( 0.0 per side ).
What do you think of it : how do you regulate it on yours?
By the way i heard talking of some Prodrive suggestions about alignment ????

What do you mean by 'open alignment'? Do you mean toe-out? And by 0,6 are you referring to degrees or mm?
Most people I have spoken to do not have toe-out in the front. I think this setup is sometimes used in FWD cars because their wheels tend to converge under acceleration and a bit of toe-out offsets this. For the Scoob you usually have a bit of toe-in or zero toe in the front.
This is a huge topic and discussed numerous times under 'Suspension'. Have a look at this page to have an idea of different setups.

I would not go for toe-out in the rear from the very beginning. It could make it very unstable. Try Prodrive settings to begin with.
Hope this helps,
Dimitris

sorry i'm not talking about camber:
For open alignment i mean front wheels \-/ not /-\ (0.6 mm)
For toe out you mean \-/ or /-\ ?
sorry but i don't have a specific knowledge.
anyway with \-/ the car understeers when pulling really really hard: it seems a FWD and it looses the AWD effect, you don't feel anymore the traction on the rear and you're forced to pull-up your right foot and to correct with the steering and this didn't happen with previous setting ( 0.0 mm ) |-| .
i thought it wouldn't be so important !

Toe in is exactly what it sounds like...imagine your toes pointing inwards...toe in. 
The bumpsteer is due to steering rods not following the same radius as the lower wishbone....so when the outer wheel gets loaded in a bend, it starts to point outwards, more and more as it gets compressed further.
Rumour has it that this is implemented to give safe characteristics - an oversteering AWD car can be lethal in the wrong hands.
