These are theoretical figures, make sure when taking readings:-
Disconnect one AntiRoll-Bar(sway bar) link.
If you have adjustable shocks, back them right off.
Set the car on level ground or four pads that have been set at the same level.
The suspension is set with tracking set and Wheel set straight ahead.
The Set Tyres(Tires) at the correct pressure. Or harder but matching across each axle.
The fuel tank should have average amount. i.e. if you normally start with 3/4 and finish with 1/8 you'd want 7/16 of a tank full.
The driver is in the car(or Dummy Weight). If 2 or more drivers, average their weight.
Set the Car heights front/back and side/side, however you want it.
Weight the car.
If you need to, move weight side to side or fore and aft, move mass in the car(Battery etc.)
DON'T change springs to adjust weights side to side or fore and aft.
Weight the car.
Check the cross weights Left Front to Right Rear and Right Front to Left Rear.
If the Left Front to Right-Rear is heavier,
Raise the Right Front and Left Rear, and Lower Left Front and Right Rear. Or ViceVersa.
Until Left Front to Right Rear is the same as Right Front to Left Rear.
Repeat until as near as possible.
Reconnect ARB(Sway Bar) link making sure it has no load when connecting, adjust as needed.
Remember to move the car back and forth to let the springs settle after adjusting and before weighing again.
