Does anyone have a program that can analyze the characteristics of our suspension or know of such quantitative data? I am interested in developing a good starting point for the modification of our suspensions. I know the usual aftermarket stuff is available but I have read where many racers change the mounting points and even the length and shape of control arms.

I am assuming that for liability reasons any production vehicle is designed to be safe for drivers from teenagers to grandmothers and for loads from one to five person plus luggage. That would seem to leave room for significant optimization potential for individual drivers.

As and example this diagram shows a static graphical analyses. If the inner mounting of the lower arm is raised this would shorten the lever arm between the CG and RC to reduce body roll. However, suspension characteristics are all interactive so the effects on steering, contact patch, etc would need to be determined.
