This one is tough to figure out. At first I thought it's possible that the springs are compressing past roll center and you're losing camber, but you have plenty stiff springs and the car does not look TOO low. If it's too much toe-in then the bulk of the wear would be concentrated on or near the sidewall, not evenly distributed across. I think throwing more camber on it might help, but based on the picture you'll need more than just -0.2 degrees.
I would actually just flip the tires on the rims so the inside is now outside and keep driving it.
