Every Japanese car/driver wants to make the chassis flex in lower traction conditions. The 2 American companies believe in a stiff chassis and letting the suspension work. It's just a design philosophy. Personally i like the high stiffness chassis better, but I mostly race carpet.
I am of the opinion that Chassis flex is Undesirable in most situations (look at the Pro-3). Flex will make the Car easier to drive, but it usually will be slower in the corners for the average driver.
My vote goes for a Stiff Chassis assembly and let the suspension do the work.
