Have you got facilities to test them?
IOr, in the same fashion, use one of those double ended yacht rigging tensioner to gently wind on more load and hold while you read off torque when pin locates.
Why would a torsion bar be any more susceptible to ageing than a spring?.....after all, a torsion bar is essentially an unwound spring and twists in exactly the same way.......unless someone knows different?Mick.
But when torsion bars are used as suspension on a car they can "settle" over an extended period so there must be some sort of permant twist as it were
While many normal cars use coil springs, the 911 suspension uses the torsional stiffness of the metal bars in order to provide the necessary spring. Like traditional coil springs, as the cars age the torsion bars have a tendency to become weak, or even snap and break.
