Hi everyone been I've lurking for awhile and love all the info on here.
My question is for guys with progressive springs and Koni shocks. When you set the damping up for all round driving doesn't the car become under damped when you drive aggressively because the springs are now at a higher rate or do you set the damping a little higher to compensate for the time you do drive aggressively?
Is it worth going to progressive springs versus a linear ones?
With linear springs once you find a good set up you will not have to adjust the shocks as much but I guess you compromise on the ride a bit.
But with progressives won't the handling suffer when you are pushing it?

 

All of this depends on your spring rates... What are they? If you have stock springs it would be impossible to "underdamp" them even on the softest setting with Konis. The konis are adjustable in rebound only. The softest rebound setting is still slightly firmer than stock. Now, the compression is softer than stock because koni felt in their testing that the stock shocks have too much compression dampening and it makes the car unstable.

Keep in mind you can over damp stock springs pretty easily with the konis... to the point that overall grip with be lessened on stock tires on anything less than perfectly smooth pavement. Also, if you have too much dampening dialed into the shocks in the front you can get lots of power-on understeer.

If your spring rates are more than stock you'll want more dampening than stock... past that tidbit of obvious information, you'll have to do your own test and tuning since the koni's are not indexed and the adjustment is not linear nor is it the same on every shock. Fun hunh?

 

Thanks for the info glagola1.
What I'm trying to achieve is to improve the shocks and the springs but keep the ride close to stock and improve the handling. I'm trying to decide which springs to get between the Eibach or the Swifts to go with the Konis.
My concern was that the progressive springs would overpower the shocks when cornering hard and encountering uneven pavement and unsettling the car.

 

Your concern should not be an issue. There is no way those springs will overpower the dampening of the Konis.

I've got a set of 500lb springs I plan on installing on my Konis. I'm not worried about it.
