From the koni manual:
Setting up
Finding a good set-up for your dampers may seem a difficult task. It is not, as long as you keep in mind to;
-Make changes to the settings in small steps (1-2 clicks at a time),
-Keep track of all changes made and their effect, -Aim for a good chassis balance fir~t, and only
then start searching for outright performance.
Basic damper set-up
1. Set all dampers at their minimum adjustment po- sition for both Bump and Rebound.
2. Carefully drive the car a few laps and increase speed gradually so you can get a feeling for the car.
3. At this stage do not pay too much attention to ex- cessive body roll, a wallowing ride and possible loss of down force that may occur because of this.
4. Increase the bump settings by two clicks at a time only, on all dampers.
5. when you arrive at a Bump setting that makes the car too harsh, back off the Bump setting one click. Note: Front and rear may need different settings.
6. The standard bump settings have now been de- termined.
7. Next increase the Rebound settings on all dampers one or two clicks at a time. Pay special attention to changes in attitude of the chassis when entering corners or accelerating out.
8. Increase Rebound settings until the car feels precise and stable. Changes of direction or throttle position should not result in drastic changes of chassis-attitude. Too much Rebound generally results in loss of grip. Too much at the front will give understeer on turn-in, too much at the rear results in loss of traction and/or oversteer on
turn-in.
Note: Front and rear may need different settings. 9. Basic set-up is now completed for this car and
track.
10. To avoid mistakes, verify that the dampers are set correctly from time to time.
Additional tips
A. When you change spring rates, expect to change your basic set-up as well.
B. A damper only functions when it moves. When the suspension stops moving due to lack of travel, the damper will not have any influence on handling. A wheel that runs out of Bump travel loses grip sud- denly and viciously.
C. Try to stick to the balance between Bump and Rebound settings as found during Standard set- up. If you wish to tighten things up, start by increasing both Bump and Rebound settings. Beware not to end up in a situation as described
at B, caused by a damper dynamically jacking the suspension up or down.
D. An increase of damping forces at one end of the car will tend to make the other end move more.
