Which setting affects sway more? Rebound or bump?

Default Which setting affects sway more? Rebound or bump?

I am trying to figure out how to reduce lateral sway in my car with KWV3's and I am too stupid to know the answer to this question. If I want to eliminate or reduce sway, should I adjust bump, rebound, or both? If I adjust rebound, do I increase it the same on all 4 corners (with a staggered tire setup) or do the rates vary from front to back?

+ Bump will slow how fast the shock compresses. + rebound will slow how fast the shock returns. I would turn up comp at both ends to start then tweek one at a time to get the blance you want. More info at http://g-speed.com/pbh/dampers.html

also remember "leaning" has a lot to do with the spring rate you are running.

"Leaning" has everything to do with the spring and sway bar rates you're running. Shock tuning may slow the rate of roll, but it won't reduce the amount of roll you'll ultimately achieve in a steady state corner. If you're looking for roll reduction, you're barking up the wrong tree by asking about shock adjustments.

Roll is all about spring rates. Whether that spring is the one that the shock is damping or the swaybar, it's still a spring

First paragraph

Bump damping controls the unsprung weight of the vehicle (wheels, axles, etc.). It controls the upward movement of the suspension as when hitting a bump in the track. It should not be used to control the downward movement of the vehicle when it encounters dips. Also, it should not be used to control roll or bottoming.

Sorry to break the news to you but if you dont want any body roll then the V3 may not be a good choice. The spring rate is not stiff enough to eliminate all body roll.

Heck with the SRC 16k springs I still have some very slight roll.

I understand what most of you are saying. The thing is, I have springs which are stiffer than stock yet the car sways just like stock. I am under the impression the damping has been adjusted incorrectly as some point (maybe by me).

Did you change tires?
