Whether you're working on a 9-second race car or a street piece, it's vital from a safety standpoint to remove tension from the torsion-bar assemblies prior to attempting any disassembly. Failure to do this can result in severe injury or even death. They are, after all, just as powerful as any coil spring, and we all know what damage they can do if they shoot out at you. The torsion bar may be somewhat subtler in appearance, but it's just as potent. Make sure to support the weight of the car with good jackstands under the framerails.
