The height of the side links at the rear needs to be the same height as the centre pivot, otherwise you'll get a mechanical lock of the pod as it trys to move vertically.

Raising the front of the links will cause the rear axle to turn slightly away from the corner as the car rolls. Basically, the outer links flattens, becoming longer, and the inner link is more angled, so shorter. Don't try it as the car becomes undriveable!

Lowering the front links is the opposite and turns the axle into the corner. Again, I've tried it on a conventional link set up and the car just flipped over.

I've also tried it on a car with a rear suspension that had a lower trailing arm, and the 2 links mounted high, above the cells. This made the rear very stable.
