I know I'll get barbequed on this one, but here is something I've had in the back of my mind, but never fully pursued the idea. Obviously this is something that I conjured up in an attempt to fabricate a suspension that would allow a deep wheel, OEM rear differential and modified OEM arms and such, and allow me to express myself with the tools and welder in my garage. Basically, it's a, "lets see if I can do this, regardless of other options" idea. My brainstorm was to cut the strut tube short, weld a bracket on top to receive a ball joint for an upper control arm, and then fabricate the reinforcement and inner mounting for the upper control arm. Then run a strut from a point inboard of the OEM strut location on the lower control arm, up through the upper control arm, and into the strut tower (where the angular difference would need to be addressed). It was more a study in engineering and of "how different can I get this and still have a suspension based on OEM parts. In the drawing below, (not to scale) I've tried to illustrate my concept. The dark heavy lines (box) are the inner circumference of the wheel showing a max OEM backspacing (dashed line) and a new modified backspacing (heavy solid line). The gray areas are the new additions to the suspension and the dashed lines on the OEM strut tube are the removed portions. With proper accounting for basic suspension geometry and proper reinforcement, I believe this to be a viable option for the masochist in all of us. Presented for your entertainment:
