For those with Koni shocks with adjustable dampening might find this helpful. Also, anyone with FK Koingsport or FK Silverline Plus-X coilovers will find this helpful as well.
I needed this info recently, so I figured I'd share.
The characteristics of shock absorbers hardly ever get the attention they deserve, despite the damper being responsible for comfort, roadholding, stability and safety.
Below is a force velocity graph of a KONI SPECIAL and a KONI SPORT shock, both designed for the same vehicle. The graph displays the adjustment ranges for both shocks. The pink area shows the adjustment range where both shocks are equal in value. The red area indicates that portion unique to the KONI Special, while the yellow area is specific to the Sport shock only.
When a car accelerates, brakes or rolls, typical damper speeds are in the (A) area. Damper speeds caused by road surface irregularities usually are in the (B) area. Whereas KONI Special dampers are more biased towards comfort, KONI Sport dampers are so towards handling.
The shape of the characteristics is of great importance: the KONI experts use this information in development.
Externally adjustable damper
These dampers are at the high-end of our range. They can be adjusted while remaining mounted on the car so that damping levels can be adapted to personal requirements in a matter of seconds.
Take the adjustment knob which is supplied and fit it to the top of the dampers
To adjust the damping force, the knob has to be turned in the direction of the arrow for increased damping and to decrease in the opposite direction. If you feel resistance do not use force, as the damper is in its end position
After adjustment remove the adjusting knob in order to prevent possible damage of the bonnet.
WARNING: Adjust both left and right dampers identically. Failure to do so may lead to unstable handling and uneven tyre tread wear.
Remove the plastic dust cover to expose the adjusting knob (fig. 2).
Depress the knob fully, and hold it in that position while adjusting (fig. 1 & 2).
The adjusting device has been provided with a number of distinct stops (clicks), each of which marks an adjustment position (fig. 4).
To increase rebound-damping, turn the piston rod one or more clicks to the right (clockwise), and release the adjusting knob. DO NOT USE FORCE!
Make sure that the adjusting knob springs fully back into position.
NOTE: 26 Series range limited to 2 clicks, 30 Series range limited to 3 click
WARNING: Adjust both left and right dampers identically. Failure to do so may lead to unstable handling and uneven tyre tread wear
Fully compress the shock absorber, at the same time turning the dust cap or piston rod slowly to the left (anti-clockwise), until it is felt that the cams of the adjusting nut engage in the recesses of the foot valve assembly (fig. 1).
NOTE: Some shock absorbers include a bump rubber concealed under the dust cover and this must be removed prior to adjusting. Don’t forget to re-install.
Keeping the shock absorber compressed make 1 full turn (360°) to the right (clockwise). The total range is about 5 half turns (fig. 2).
Extend the shock absorber vertically for at least 1 cm without turning in order to disengage the adjusting mechanism. The dust cap or piston rod may now be turned freely.
WARNING: Adjust both left and right dampers identically. Failure to do so may lead to unstable handling and uneven tyre tread wear.
