Looks like body roll mainly. Doesn't look like a particularly fast corner anyways.
Correct, its body roll due to the lack of rear springs on the modern cars.
they design the upper suspension arm to provide the "spring" and only run dampers. Spring rate is altered by a air chamber on the damper. These units are much smaller and more compact than the older coil springs or more recent torsion bar
the teams do this to make the rear end more supple and that provides better traction.
With the smaller diffusors in use this year there is no need for a very stiff rear end since the flow is not as affected as last years double diffusors when the rear of car rides up and down on bumps.
