for what it's worth, here are two alignments that worked for me:

before PSS9 and GT3 LCA (with Eibach lowering springs)
front -1.25
rear -2.25

after PSS9 and GT3 LCA
front -2
rear -2.5

you probably need adjustable rear toe arms if you lowered that much, otherwise you will go through rear tires in an amazing pace
