Eibach + Alignment +/- Camber

Hi all alero owners,

I'm from France, and due to your forum I decided to buy Eibach springs for my 2.4 Alero mod 2002.
The difference is enormous. cornering is much better.

BUT, my alignment seems to be around +4°, and camber can't be changed.
does anyone knows the value of alignment (in Europe we are used to say it is between +2 and -2°, depending on the make, model and the way they check it, with or without loading the car)
Concerning camber, same question : does anyone knows the value especially with eibach springs ? And is there a way to modify it ?

Does anyone experienced with Eibach springs and alignment and camber ?

Thanks all
