Suspension Geometry

I've been doing some research on suspension and steering geometry and have come across a couple of nice programs for calculating suspension dimensions. Although this is not a completely scientific art, it certainly takes out the hard math's aspect, out of calculating things like roll centres, wheel scrub and dynamic camber/castor changes.

I've made a basic design for the layout, all I have to do now is see if it will fit, unfortunately things are not looking good as I was hoping to retain the original frame horns, and it looks like it will lengthen the wheelbase too much if I try to fit the suspension in the position where the beam originally was. I guess if that's the case, I'll have to decide if I can justify cutting the frame horns off, I suppose I could always get another pan.
