It's more than a sway bar that controls roll. Taller spindles or ball joints move the roll center up and closer to the center of gravity. This really helps control the roll and inspire confidence while auto crossing and open track. The combination of shock AND spring rate dictates ride quality. This and chassis stiffness play the largest roll in doing so. We tested all this at XV which everyone has forgotten by now. As far as bolt in shocks we only have 2 decent choices that are mono tube style and neither one are double adjustable. The good stuff costs. Years ago we did a program with AFCO to get this dialed in.
