So I said well 4-link can give me the best of both traction bars and anti-squat, so I been hard at work in my notebook doing all the math for the materials to make sure that they don't fail under load, and in AutoCAD Mechanical I been designing and performing the FEA on the various mounting brackets and links. This is something I was working very hard on but I took a break, I only recently got back on the designing. I figured out how to make the mounting for the front links so the cross member portion clears the driveshaft including it's movement of course, the mount also serves as a cross member which will really make the rear end rigid, the only problem is the weight is just severe, the whole suspension system seems like it would weigh a good 150-220lbs. Most of the weight being in the brackets and cross member because all that is 1/4" steel plate or the cross member being 2-1/2 x 2-1/2 x 1/4" steel square tubing.
