All swaybars are is a dynamic spring that reacts in roll only.

Going to a bigger swaybar will reduce roll since it resists roll motion, but when you reduce load on the inside tire from accelerating the inside from will have dramatically less load since it will be transferred to the outside rear.

I think of load like this.

No motion sitting static
[720][720]
[380][380]

Forward acceleration no steering
[640][640]
[460][460]

Braking
[900][900]
[200][200]

Left hand turn accelerating, this is where the swaybar starts to do what its designed to do. The stock bar on my car provides around 160lbs of resistance. Going to a bigger front bar will reduce load to the inside wheel which is also the drive wheel. Shown crudely below. As you can see you have a 2-3" contact patch with only 460/lb of load on the drive wheel.
[460][730]
[400][610]

From the pictures what you're seeing is dynamic camber loss under extension. It doesn't help the fact you're inside rear is picking up transferring more load to the outside front, which if you look carefully at the picture is deflecting really really badly and probably overloading from what I guessing.

Being your car is Mcpherson you really fix the contact patch issue on the inside front without reducing body roll a significant amount which bars aren't really gonna fix.
