Here's a quick run through on setting up.
1: set the tire pressures (on race cars set it to your hot pressures)
2: set front and rear ride height
3: check corner weights
4: adjust spring collars to get even cross weights
5: recheck ride height
6: align the car
7: recheck corner weights and adjust cross weights if necessary

Example
LF 375 RF 340
LR 610 RR 635
Now if you have exactly the same ride height side to side on the front and rear, then go tighter on the spring perches on the RF and LR evenly. The reason I go up is because the springs tend to settle. But if the LF is a little high, loosen that collar. After you adjust the collars, recheck ride height.
