In addition to what these guys have said about tuning droop for response, you can also tune for the bumps or irregular track surfaces.

For example if you going through a sweeper and on to a main straight and your car spins out from hitting a bumpy section, you can add droop (down travel) to keep the tires in contact with the track surface.

Also, for bumpier tracks, you'll want to run more droop. In general, for super smooth carpet situations, you can experiment with limiting droop to tune to your preference for response. As most guages measure in 1mm increments, you can try 1mm at a time so you can see the difference. Don't be afraid to experiment. I t also helps to make note of your changes.

One note: It is best to measure droop without shocks installed and without the swaybars installed at a consistent point on your arm or upright. (Serpent often recommends this for their fuel cars). Set the droop (using guages) the same from left to right. The front and rear can be different settings to control your chassis balance and responsiveness.

When done without shocks or swaybars, you can then install the shocks one at a time, while rechecking the droop for consistency. If you add the shocks and notice a change, your shock is likely too short, or needs a rebuild. The same with a sway bar. You add it in and use the guages to balance it from left to right by adjusting the sway bar mounting points (usually a set screw on a ball joint). In this way, you can sort out suspension problems (symmetry) while you are adjusting your settings. You combine the adjustments with inspection and maintenance to ensure consistency and top performance.

One last item, make sure your shocks are long enough to handle your droop setting. If the shocks are shorter on one side, you may not be able to to have consistent performance from left to right.
