It is called When this happens, the torsion bar withstands the torque and will quickly return to its original position after removing the torque. The bars retain a memory of the direction they are twisting, if they are twisted in the opposite direction the spring rate will be compromised and the bar could fracture. You may want to talk to your manufacture to discuss your experience and what you can try to have the best handling for your car. Also, remember not to over tighten your stop or torsion arm bolts.
