Suspension Gurus, I need some assitance. I can't tell if I can adjust the ride height with the setup in the picture below. It looks like you can based on the spanner nut but underneath there are no 'threads'. If you can, what's the correct procedure...I appreciate the support!

Help!!

Threaded collar is hidden within alu nut right below lower spring plate. Though it might be stuck and rotate with nut.

You should be okay--it just looks like your nut is dead-center on the threaded piece. Good luck--my nut and threads were seized. Attached is a picture (carnage) of my front left if it helps you see how how it looks when you compare the length... Fortunately, used from 928 Intl had a reasonable price.

Ok, i tried turning it 8 times; essentially 1 small turn per notch. However, I didn't see any movement. It didn't appear to be seized from what I could tell as it did move rather easily with a cheater bar. I was turning it counter clockwise fwiw.

thx...

It takes a lot of turning with the fine thread and you probably will not notice a difference until lowered back onto tires.

The threaded part may also be turning when you turn the collar. Basically the threaded part fits onto the shock housing and can spin with the collar if there is not enough friction between the threaded part and the shock housing.

In adition to the question regarding the spring pre-tension:
Has anyone tried adjusting the damper caracteristics of these Konis? As far as I know, there are no adjustment screws, but Koni usualy makes their products dismantable, in order to change the dampening oil.
I would like to stiffen them up. My daily car his a firmer ride than this sporty Porsche...

On the "regular" red Konis, this is an "internal" rebound-only adjustment that requires fully compressing the shaft down into the body to engage a cam. On these shocks you will see an Allen hex hole in the tip of the shaft. You would need a LONG Allen tool like this one:

To adjust them you would turn the adjuster clockwise to increase the rebound dampening. There is about 2.5 turns total range. Stay away from the extremes by 1/2 turn.

Koni reds can be converted to "externally" adjustable rebound by Koni USA in which case there is a **** adjuster on the end of the shaft and the direction of adjustment is reversed. A compression adjustment port may be added to the side of the shock body by Koni as well.

Welcome back Bill!

Brad - It's pretty time consuming--you'll think you have it right, check it 2 days later and it'll be off again; or you'll adjust the oposite corner and it will push the other side down... It's spring tension kung fu--the car has to be in balance

hey guys ..yes after several turns...finally saw it moving...I appreciate all the help...

for me, I have my car up on the lift so I can have the tires off and adjust by the threads all at the same time...here's to hoping this works!

bill i presume that tool that you reference adjusts the 'stiffness/comfort' of the shock?

These would not adjust
