Mdoc-As far as I know in F1 they have always gone for a stiff tub even before the aerodynamic downforce was so well developed. On these cars with wide tires, camber control is very critical and I think that might be what influences their design. You can change the camber a full degree on my touring car and it is hardly noticable. You just wear the tire poorly. I plan to do the chassis flex experiment myself with the JRXS which is about 4 times stiffer (measured) than the XXXS after I get more cosistent lap times with it. I can remove 6 upper plate support posts and reduce its torsional stiffness by that factor of 4.
