Upper Control Arm Cross Shafts

I think you will be happier that way, as that x frame has no torsional rigidity. It relies on the body to stiffen it up such as the body mounts will provide...(great for noise isolation). even if you installed solid body mounts the frame will still transfer suspension loads to the body eventually disassembling it if the loads are high enough. At the cost of a less than stellar handling car.
