In the photo you posted and in regards to the upper control arm angle, the suspension is unloaded, that is why it looks as it does. At designed ride height the upper arm will either be parallel to the lower or angled slightly down toward the center of the car. In comparing the angle of the upper control arm between various suspension systems, modern theory has the upper arm angled down toward the centerline of the car at ride height. That way camber goes more negative in bump and the roll center tends to be lower.

Regards,

Andy
