I often jack my car up and put it on 4 stands , mainly because i find it easier to work on .
That way i can work on both the top & underneath it .
I have a large floor jack that i position under the centre of the G/box & jack the front up first , i then position the stands under the flattest parts of the subframe .
I then position the floorjack under the rear subframe at the back , i take my time jacking the rear up , so as not to put too much weight too quickly on the front stands because they can move and the car
can slip off the stands . I make sure the 4 stands are at equal heights .
After i have the car sitting on all 4 stands on its own , i give it a "GENTLE" rock to check to see if it is stable , the last thing you want is it falling on you if your under it , and to be extra sure i put a couple of rims or large blocks of wood under the area that i am working on.
I just recently modified 4 stands to suit both my mini and my Falcon because the U shaped piece on the top of the stands was too unstable , ie; ( metal on metal ) so i had some flat 10mm plates welded on instead , i then glued some thick rubber on the plates so they should work well .
