Interesting find.. I'll have to pump some of my numbers into it from past projects and see what it does.. Probably won't get to it for a week or so.. Need to get the GT moved around in the shop and get back to work..
Works well if your A-arm chassis attach points are parallel to the centerline. I had to download OptimumKinematics and use that and CAD software to do the design on my Tornado, which has the upper and lower A-arms attaching to a frame that is tapering in the front.
