"The Chaparral Frame

The basic frame of the Chaparral 2 is a most interesting and unusual piece of engineering. It was conceived jointly by Hall and Andy Green of PlasTrend, Fort Worth. The design requirements laid down by Hall called for a maximum frame weight of 150 Ib, combined with an axle-to-axle torsional rigidity of at least 3000 lb-ft deg."

3000 lb-ft/degree ~ 4040 Nm/degree

Are all modern cars so much stiffer than an early Chaparral?

Please say it isn't so !![sadeyes]

If you really want a high RTI put a cylindrical joint in the middle of your chassis, ie articulate the chassis.
