Stiff Front Sway Bar Thoughts

SeeThruHead

I always come back to this thread when trying to understand sway bar stiffness on the Z.

I found this today that seems directly related to the conversation.


From the pages of High Performance Handling Handbook by Don Alexander:

"There are situations where increasing the stiffness of an anti-roll bar will have the opposite effect. Most stock vehicles have excessive understeer because it is easier to control and provides more stability for the average driver than a vehicle that oversteers. A big part of this comes from excessive body roll, which induces too much camber change, and a good portion of the front tire contact patches loses contact with the road.
In this instance, adding a stiffer front anti-roll bar, which would typically increase the extreme understeer, actually reduces the understeer by reducing the body roll-induced camber change. The front tires now stay in better contact with the road surface, creating more traction and reducing understeer."
