So I've got a coilover system on my S. The shocks are Koni Yellow and the springs are an unidentified brand. The suspension was on the car when I bought it about 5 months ago.

The ride is rough. I don't mean "firm", I mean absolutely spine jarring. The suspension doesn't so much absorb bumps as it just crashes over them with. Large bumps hit so hard it literally sounds like something is breaking on the car. Uneven and broken pavement is just torturous. I live in Atlanta and we have some very bad roads here.

All of this for a 1.5/1 inch drop. I'm seriously beginning to question whether it's worth it or not. I have the stock suspension sitting in my closet. Before I go back to stock, are there any last ditch efforts I can try?

The shocks are adjustable, but I worry about bottoming the suspension if I soften them too much. The tires are the OEM RE050s, which are known for their rough ride. I'm going to go with a slightly smoother riding tire when these wear out (likely the Continental Extreme Contact DWs).

Anything else?

 

Aren't the Koni Yellows adjustable?

 

Yes, read the whole post.

 

Raise your car up a bit, you might be too low.

A friend of mine just installed some used Konis and they didn't have any bumpstops. I'm assuming the other guy wanted his car as low as possible.

The damping adjustment on those is rebound only so running them a tad softer may help depending on spring rate.

If you can pull up a driveway and take pics of the damper assembly then maybe that might help figure out what's wrong. A picture of the height of your car will also help.

Koni's from what I've heard in the past are actually a tad smoother than stock.

 

I'm not even that low.


The front is a tad lower (maybe 3/4" fenderwell gap).

 

Try setting your shocks at full soft first. If they are valved correctly, even the softer setting will be a good enough match for the springs

 

I don't have the yellow top adjusters for the Koni's anymore. Do I need those or can I use something else?

Is clockwise firm and counterclockwise soft?

Lastly, how do I access the adjustment for the rear shocks?

 

Soft is clockwise. You get to the rear shocks through the truck. Take out the spare tire to get to the right rear and pull back the interior pieces to get to the left rear. You don't have to use the koni adjuster, it just makes it easier.

 

So to be clear, any adjustment on the shock will only be for rebound? Can I not adjust compression firmness?

 

Only if you see a knob on the bottom part of the damper otherwise it's a rebound only adjuster at the top.
