Right, you do not actually put weights around the cars, you're just adjusting the springs (but you can move weight around, like the battery to the back of the car). You can get the corner weights right, and the ride height right, by taking your time and watching the scales. Try downloading that little program from Performance Trends that has the demo and try "raising the coilover" and then "lowering the coilover" and you can see how it affects the other wheel weights along with the ride height.
