A Supra chassis that is stiffer than the Lexus LFA with a stiff suspension would not only be miserable to live with, but would probably perform poorly except on perfectly flat pavement or a track, and even that is questionable. This goes the same for the Z4, even being pretty stiff for a convertible; putting soft suspension on a chassis that is already has flex because it is a convertible is not ideal if performance is at all being considered.
Take an example from another type of motorsports--Motogp (I know. Motorcycles again, but try to follow because the same principles apply). They learned that they couldn't just keep making the chassis stiffer because in a lean, where the vertical suspension was negated, it was necessary to have chassis flex. Similarly, if the Supra had stiff suspension and a stiff chassis then the car would be bouncing down the road, so something had to give. In their case, a stiffer chassis with softer, adjustable suspension is the better setup than the Z4's softer chassis and stiffer suspension, yet the Z4's hands were tied in this situation.
