Default Koni adjustments looking for feedback

Alright I used search several times and can't find any information from people that have installed Koni/Eibach kits. What is a good setting for the Koni's. Once they are in your pretty much stuck with the setting.

Default ?..different types..more info please..

how about a picture? Most C-O suspension are adjusted by the large nut-rings and you adjst them according to how you drive and your needs.

Default The Q was Konis, not COs. Konis have adjustable rebound damping only, adj. to critical damping...

for the particular combination of spring rate and unsprung mass. If a spring/shock kit designed for your car, the mfgr should supply the correct adjustment instructions. Otherwise, adjust per Koni's instructions, usuely 1/2 turn above minimum. Further adjustment is to be used only to compensate for internal shock wear over time, not an "optional" adj. An overdamped suspension is a downgrade from an optium, critically damped suspension.

Default The front and rear Koni Sports have different amounts of adjustment...

Konis for our cars are adjusted by compressing the shaft completely and then rotating the desired amount to increase/decrease rebound damping.

The fronts can be rotated approx 1 3/4 turns (630 degrees). Each 1/4 turn = a 14.3% increase in damping (assuming a linear rate).
The rears can be rotated 2 3/4 turns (degrees). Each 1/4 turn = 9.1% increase in damping.

I have Koni Sport-based 2 Bennett coil overs on my car with 450# springs in front and 500# springs in the rear. My front shocks are set at 1 full turn (57.2%) and the rears are set at 1 3/4 turns (63.7%).

I've experimented with different damping adjustments and different springs. I've found the current damping to provide a good around-town ride while still being controlled at speed. More damping did provide more control but didn't provide the ride I wanted day-to-day.

Most believe that your Eibach springs are in the 350-400# range. As a result you may want to choose slightly softer settings than I've listed.

Good luck

Default There is but one optimum, "critical" damping for any given spring/mass linear vibrating system...

Underdamping or overdamping is less than optimum, independent of the application!

Default Great theory, but our cars don't live in a linear environment...

High and low speed inputs, differing frequency, etc. put a lot of demands on a damper. Although better than stock, Konis or Bilsteins are still relatively unsophisticated. Real world, this means we need to make compromises in suspension tuning. So, unless you invest in a highly sophisticated and expensive system like Stasis Motorsports pick your trade-off.

Default Well put, but the car's mass is not a constant. For what load do you tune it?

Mine is overdamped empty but pretty spot on with 4 passengers and luggage.

Default Again, your Q relates to CO adjustment,, not damping. CO adj. relates to static ride height, ...

Totally unrelated to subj. Koni rebound damping adj. What are you asking for?
