How are you lifting the whole side at once? On the pinch weld? Do you use a pinch weld puck?I regularly lift the whole side of the car for swapping wheels at and before the track and jacking rails are overrated. There's nothing earthshattering that they provide for the added cost and weight.
Lifting the whole side of the car and placing on jackstands is easy and the savings of 30 seconds per side is not worth it.
