From an article on the 2001 Z06, it states that "the fixed roof and lack of the big hole in the back for the coupes hatch make the hardtop 12% stiffer in torsion than a coupe with its roof in place.And for the rocket scientists out there,Torsional frequency is 20hz for the convertible,Coupe with the roof panel out is 20.5, and jumps up to 22hz with the roof on. The Z06 is a stout 24hz."AdrenalineJunky said:Does anyone have some numbers for torsional and bending rigidity properties between C5 family... (coupe, convertible, FRC)?
Thats a TON of info!! :thumb: Great stuffleaftye said:All I've seen is was what published in SAE SP-1282. I've copied those numbers into this thread: http://forums.corvetteforum.com/showthread.php?t=984927
