If you don't have the Torin T43004 type jackstand and you have regular stands then you can use hockey pucks, or in my case I just used 2"x4" boards overlying the plastic BMW jack points, which have held up great but take some balancing when lowering the car down onto them.
This method only works if your car is high enough to get a jack to the center point.
