The pucks are certainly a good place to lift the car- but they are certainly not the only places to lift the car. They are designed specifically to provide convenient points to put the car onto a shop lift. For a floor lift and jackstands, use them if they are convenient, but don't be constrained by them. The pucks are just plastic pads that are inserted into a structural steel rail. It's the rail that is reinforced for supporting the car, not the pads.
To lift the front, I use a floor jack with a soft pad, and place it about 12-16" behind the puck. Lift the car, and place a stand under the puck. Lower the puck onto the stand, and do the same for the other side. __________________ *Except 318ti
