aluminum K frames

Denny I can't imagine the aluminum not being street friendly if braced right. Mercedes and the other Luxo boxes have Aluminum chassis components and most are cast not forged. I'd like to see what kind of abuse one could take before braking. Heck the Chevy Impala has a welded together aluminum front k member and I've seen them take a beating in an accident. I bet if you made the main members out of honeycomb you should be good.
