I don't like to play too much with the toe setting as it can hurt the top speed & turn in behavior. Obviously I only did some light change. According to the tire data it can run more camber...
Since adding camber hurt braking I thought about just adding more camber on the back tires.

I got gold eventually as it is much easier to drive with the small change on the camber. It's not well driven, but it seem to work out.
