harmonic resonance on anything metalic is a fucker, bridges, conrods, propshafts etc

i really dont see the appeal of single peice,
is it rotational weight, overall weight, unsprung weight or loss of torque that may be the issue in this situation?
V8 in a firenza with live axle, cant be weight biased i guess?

p.s i think everyone will get the idea when you use a flagpole as a graphic thaught!
