Very good thread guys, but all I have to add is been there done that. If you what to find a geometry nirvana give up. I spent six months studying countless chassis design books and geometry articles for every type of car imaginable. My head hurt for weeks afterword. What I came up with is a untested compromise of every thing I absorbed. Sorry there are no numbers to give out did not use them. If you want to design a suspension system start at the corners and work inward at ride height, thats the best way I found.
I'll be watching,
