Put Koni's on the GLH-T, WOW!

[fuzz's84Daytona]

This things feels like it's riding on rails. Just a few questions about them. Even if it's set on soft, does it still feel stiff? About how much does it lower it down? Thanks.

The 'feel' is more the stiffness of the springs you have and their pre-compression. The Koni's will absorb the impacts and smooth it out a tad on soft, but the ride is still pretty stiff if you have stout springs...

[turboshad]

Like JT said, the firmness you feel and the realized drop comes from the springs. The only way the struts will lower the car is if the spring perch is in a lower position than the previous struts. The adjustment you have on the Konis is a rebound adjustment so it will control the "bounce" in the springs. With a soft rebound the spring will decompress quicker after it compresses from a bump in the road. If it is too soft and this decompression happens too fast you get the bouncy uncontrolled feeling. The stiffer the springs, the more control/rebound you need and would therefore want the struts set to a harder postition.

I thought it was compression not rebound? When I tightened mine up, the initial HIT/BUMP was firmer than before, so to me, that's compression.

Yeah, I thought the reds allowed for adjustment of compression while the yellow allowed for compression and rebound.

Also, how do you adjust these darn things? I can't find any instructions with mine.

Struts, on top with the adjuster, rears, remove the shocks, compress and turn.

Front's use pliers-ick or this-

The original red GLHS Koni's are very stiff, even on the soft setting. I installed the yellow Koni coilovers with 450lb eibach springs and it rode much softer, who would have thought.

Out of the box, I assume they're on full soft? What settings would you guys suggest for the front and the rear for a road course?

Set them in the middle to start, :thumb:

I've been riding around for acouple of hours and I'm getting used to them, but what a change from stockers. For the price that I paid for these things(really cheap), I don't mind having to get used to them. Thanks for letting me know what to expect.

If you check out their catalog, all single adjustable shocks are rebound adjustable. This is also condusive to any other single adjustable shock I have seen. If you want to have compression adjustability then you need a dual adjustable shock.

For K based cars I run the rears as hard as I can get them and still have them decompress equally. Then I adjust the fronts to get the car balanced the way I like.

Yeah, they got back to me, its rebound, which totally doesn't make sense, :confused:

Are you running 450lb spring front & rear? What model car are they on?

450lb front, 350lb rear on a 1986 GLHS. Check out the suspension here.

450lb springs? That's WAY stiff for our cars. To each his own I guess. I'm running the yellow Koni coil-overs and the car has mid 200's in the front and 300's in the rear and my car to me, is very stiff. I think the factory spring ratings for the Shelby Chargers is like 250-280 in the front and just under 200 (like 180) in the rear. The only reason the car has the 300's in the rear is because I didn't want to spend the extra money at the time, so I stuck with what I bought originally. I HAD 330 or 350's all the way around and I about shook my car to pieces.

Well if you think about in the most simple way....

If you have upgraded springs that will in itself slow down the compression stroke Higher spring rate will compress more slowly and less travel used as well

but the stored enrgy in the spring will now bounce back harder/faster 450 lbs pushing instead of the 200 ( assume same compression of say an inch) so now you have to control more rebound speed.


one the bikes i would add rebound and dial out a little compression when i made a spring change.

spring and shock stuff is weird.... I imagine that i could be really wrong on this but that is how I make sense of it

then add bump steer and high and low speed stroke adjustments:confused2:

Sorry, I mean that it doesn't make sense its rebound, when I adjusted mine, hitting bump was a big change, so that's why I thought compression.

Your analogy is good though on why they are changing rebound. :thumb:

[T-Bohn]

agreed on the change hitting bumps they say rebound only but the compression stroke is slower as well... I mean you stand on the bumper and it is slower both directions. I get the feeling that the circuits are both changed slightly
