Not sure your driving style; mine is more straight line/with wide open acceleration from a stand still.... I'm only running about -0.5*rear camber & factory-0.8*F
I'm sure your alignment guy dialed the eccentric bolts on the camber arms as much as he could (shortened distance,to pull bottom of tire in) they have markings on them,,,,but when you go more positive on the camber (wheel lean out) you in turn give yourself more toe (wheels point in) .
Your toe setting is great; I have basic Kinetix rear camber arms from Z1 & have them shortened as much as I can (without having too much + toe)
My toe eccentrics are adjusted all the way negative & I adjusted the camber as far positive as I could, without letting toe get too positive.
One adjust directly affects the other.
As far as the front,upper arms are needed for that correction.
Good Luck & be sure your Toe adjustments stay very close to where they are now.
