What I would like to see someone do is use a set of composite leafs, Watts Link, and our Torque Arm (not the whole kit, just the torque arm). The Watts link would do a superior job of locating the rear and composite springs have much quicker reaction times than steel springs and lower unsprung weight. For traction issues and preventing spring wrap our Torque Arm is perfect for a composite spring because, unlike a traction bar, it doesn't load the front spring eye. Since it is centrally located and has bind-free articulation, the leaf spring would only have to support the car, the torque arm would handle the torque load. I would bet this setup coupled with a good set of dampers could rival any link style suspension out there...
