That's not right what he said. In the front you only can adjust toe, but they can check the chamber, caster and K.P.I. just as well! If one of the last values are wrong, then there is something crooked

(BTW, when lowering your car, some of that values could be different from manufacturer adjustments)
In the rear you can adjust toe and chamber! The adjustment range is not very wide, when looking to your pic, i think nothing can be done anymore......
Probably you need some new parts to fix the front wheel suspension, or in the worst case you'll should align the whole car..........
