My brother just got brand new Koni Yellows and H&R 'Race' springs and on the softest setting it's smooth like stock but at hardest it bounces like crazy, just a literally non-stop bounce-bounce-bounce even where the road doesn't look bumpy or anything. It's not like a quick, harsh bump but like a bungy cord bouncy. On middle stiffness on the shocks, it's stiff and not bouncy but I thought it was wierd that it's so bouncy at full stiffness. Is it possible that the springs or tires (the tires were crappy, mismatched at the time) are too soft for the stiffest setting of shocks (is that possible at all?)? I was just wondering/curious and was expecting it to be stiffer than what it is now (at about middle stiffness).

Thanks for any help, input, discussion, whatever. I hope what I said makes sense

With a really stiff setup like that you should be feeling every little imperfection in the road even if you can't see it with your eyes. Your car absorbs the bumps instead of the shocks absorbing them since you are set at a really stiff level.

 

At the stiffest shock setting, you are severely overdamped so the ride feels really rough. You may very likely notice your own body bouncing on the seats of the car as you and the car shell are not moving in unison. This is becasue there is so much rebound force that you are keeping the car from going through it's needed wave of motion. Although the shocks are stopping the car before the cycle is through, the items insdie inculding the people still have some energy remaining and will continue moving. This is because you have tuned in too much rebound damping. At max setting, the shock makes twice the force as it does at min setting so the adjustment range is quite large.

If then car is pretty good at full soft and pretty good at a mid-range setting, why would you complain if it gets rough at max? There is such thing as too much and you have found it. You will probably find your happy spot somewhere between 1/2 and 1 turn from full soft. More than that will probably be too much.

 

I wasn't complaining, just wondering, cause it felt more bouncy than harsh/hard but I guess that's just how it is on roads

Thanks for the comments/info

 

It was happened to me same like your brother setup but I have Skunk2 Coilover/Koni yellow.. ANyhow the car was bouncy crazy even where the smooth road.. I decided to call my friend worked Ground Control and told me why can I try to get the Ground Control Top Hat. SO I bought it from him and then put the top on my car.. I can tell and feel the difference between stock top hat and Ground COntrol TOp HAt.. IT wasnt super bouncy like before, it is a minimal bouncy.. Im happy my setup..

 

Hmm, how would the GC top hats help? You got a pic, maybe of your setup? Thanks

If the car is low enough to be regulalry hitting the bump rubbers, the ride would be very harsh and likely bouncy. The GC upped mounts allow the bump rubber to be recessed upward into the mount about an extra inch or so giving you a bit more free stroke before it hits the body.
