Finally got the Koni/Eibachs on that I bought long ago from Scott Mohr. DAMMM...THe car is on rails, BUT - it is TOOOO stiff for the highway. I'm getting beat to death. I understand that there's a way to adjust them in the car - I have the long T-handle...but don't know how to use it....any BTDTs??

TIA!

You can adjust the rebound BUT NOT THE COMPRESSION so you can change how the wheel moves down JUST not how stiffly it resists the wheel moving UP ! To use the tool the single top shock bolt must be taken off and the shock fully compressed and then you turn it to change the rebound.

Thanks, Jim.

Which way (looking down on the top of the shock) adjusts more/less rebound??

OK ....ADJUSTING DIRECTION

Clockwise = Firmer
Counter Clockwise = Softer

The piston MUST be in the fully depressed position in order to engage the adjuster. I've found that it's a lot easier to use a shorter T handle Allen wrench to depress the piston. In the front you can just "stand on it", but in the rear you'll have to climb into the hatch area to get the right angle to keep the piston depressed.
DO NOT, I repeat DO NOT remove the Allen wrench from the shock before the top of the piston has come back up through the hole. If you lose the alignment it can be a bitch to get the top of the piston back up. I've found that front full soft and rear about mid way works well in my car.

If you do not know where the shocks are now set, engage the foot valve and turn counterclockwise until the stop is felt ...counting precise fractions of a turn as you go: You are now at full soft rebound - and know how firm it was set.
There are ~2.5 clockwise turns to full hard - so use the above info to determine where you wish to adjust to. IIRC, the adjustment is not linear as turns are added, so " a little is a lot" . For street use, I've set +1/2 on front, +5/8 rear.

Ok, I just have to ask. What is the best method for compressing the shocks when installed in the car. I read J.B.'s post, how do you keep it compressed while you turn it?

Richard S

Use the long Koni adjustment tool....basically a long allen wrench with a handle on top.

Garth:

So, you set yours 1/2 and 5/8 turn from full soft?

Bill51sdr

How "long" is this tool? Is it commonly available or do I need to go thru Koni?

DR sells it for a good price:

Doesn't Koni make a sport model shock that is externally adjustable?
I have them on the 914, Rebound only. I love how they ride on the freeway full soft. Track conditions determine how much rebound to dial in. Forgot to turn them down leaving an event several months ago. Thought I was going to die.

Garth S

Bill,
Correct: I've played with more rebound dialed in, but didn't quite like the feel - seemed to 'deaden' the overall crispness of the suspension.

Thanks Bill I'll have a look.

OK - bout to give this a shot...just want to make sure I don't have my shock blow apart from me doing something wrong!!
Here's a (poor quality cam phone) pic...Appears to be a nut around a threaded bolt sticking up, and then a washer under it.

I removed the nut and washer - do I depress on the top of the bolt with the long hex?? (If yes - how/where does the hex 'grab'...it is smaller then the 'bolt' top.??? And - about how far does it take to fully depress? (Easier with suspension loaded - or with car in the air??)
Sorry for all the questions..
