Chassis Stiffness Zero Roll
I had a gen one Laser back in the mid 80's with a dual shock zero roll system. The frame would flex so much during lateral load transfer that the front pulley would hit the battery which was over a quarter inch away. The car would take a set in the corner and then just break away. Although Brian is turning checkers into chess I do agree with him that chassis stiffness, in a zero roll car, might be a bit under appreciated. Additionally I like to run a rear anti roll bar on my zero roll cars which increases the importance of rear chassis stiffness.
