Softer springs or not, that is the question

[bobl]

My car has the 3 link setup. When driving on bumpy roads it would trigger my pacemaker and my heart rate would go crazy. On the advice from this forum I switched to 250 lb. rear springs. I also added some foam in my seat. It made a huge difference. My pacemaker very seldom triggers now, so I've got proof it rides a lot smoother. I preferred the handling with the stiffer springs, but everything is a compromise.

You, Sir, get an exception. YIKES!

One thing is that you cannot change spring rates without affecting handling. Maybe not in the envelope that you normally drive in, but definitely at the limit (on the street, known as an emergency maneuver). It may also change where the limit is. Unless you are going to do skidpad testing, go with a known setup from one of our resident experts.
