Do you mean the spring tension adjuster.
Your initial reaction will probably to use it to create more pressure to the springs thus making it firmer, but this is probably not the proper purpose. if you want to stiffen your setup use firmer springs instead.
Some people will use it help in getting rid of tweak by creating different pressures on each shocks in hopes of creating overall balance, but other says it will actually worsen the balance of the car because it is not equally distributed and you did not really get rid of the tweaked chassis. I just use them to make sure the springs is not floating in the shocks and i try to make at least the opposite side equal length.
