I don't have my 4BW yet, but I'm also looking at how to get the car on jackstands for wheel changes, brake bleeds, etc. For the front, it looks like I would be able to lift via the front pinch weld with a slotted puck, and place a flat-heat jackstand on the unibody frame with the 2 large holes exposed, just behind the pinch weld.
For the rear, it is it not possible to jack up from the subframe just behind the rear diff? It does look recessed, but that is strong, thick steel. Lift that, and the rear should come up easily, allowing one to put jackstands on both sides in the rear. That's how I've lifted many cars in the past. The rear bumpers of both BWs slant up pretty high, so a long jack would be able to reach the rear subframe. Pucks may be required if it's recessed.
Obviously, I don't have the car yet, so I can't test out my theory. I'm just spitballing here.
