While cruising around reading stuff on Callaway Twin Turbo Corvettes, I came across a factoid about the body stiffness. The C4 was measured at 17 Hz, while the C5 improved this to 23 Hz. The C5 is apparently much stiffer and more solid than the C4 was. Anyway, I thought this was an interesting benchmark. The classic Aurora had a chasis stiffness of 25 Hz, and the new Aurora apparently improved on this (no idea how much). I thought it was interesting. I don't know how the resonant frequency relates to body size, maybe a 25 Hz 200 in. car isn't actually as stiff as a 23 Hz ~150 in. car. But still, it's pretty cool that the Aurora is possibly stiffer than a C5.

The G-body chassis was always the standard for good solid chassis. I suppose thats why the G never needed strut tower braces unlike its H-body cousins (of similar weight).
Very cool factoid 40...thanx!

I did some searching around and found some info about this at the site noted below. The 2001+, according to what this site says, does have a stiffer structure than the Classic, but the improvement is not stated. media.gm.com/division/olds/products/aurora_chassis.html________________ GM!!! BRING BACK OLDS!!!
