    Torsion Bar Pre-Stressed Service

    Re-stressing allows bars to have greater elastic twist angle and hence more wheel travel. It also drastically reduces bar settling eliminating a need for a racer to bounce a car up and down in order for it to settle at the correct height. During pre-stressing the bars are twisted within the plastic shear zone over a specific angle, unloaded and repeated two more times.

    The Torsion bars’ strain curves are carefully monitored during the procedure. The procedure causes compressed residual stresses at the outer boundary of a bar increasing its yield strength. Ultimately, this saves time and, more importantly, conditions the bar for immediate on-track use in while also increasing the bars overall longevity.
