How to build a SuperStock k-member

Boxing the K in,your actually adding metal for a stiffer result.Just sayin..
You might be right , then again the mods might put stress on parts that have not been re-enforced , have not done the calculations or worked it out , would take to much time . You would be surprised how a small change can affect a design . Just not sure I would be comfortable making these changes on a STREET driven car with resulting liability in case of serious accident .
Nice work anyways , just sayin , after 30 years designing and putting up office towers .
