I talked with Ron Sutton today and he told me to send him the Performance Trends file for my car. Before doing that, I double and triple checked all the numbers and added a few that I didn't have yet. I discovered that my front roll center was 2.5", not 3.5" and that my rear roll center was 14" and not the 10" I thought it was. Also, turns out I have zero caster, not the 6 degrees I thought I had. So, I think I know at least a couple of things Ron is going to tell me to change.
