Coil springs are an improvement because they are adjustable and easy to change. Torsion bars give the car a slightly lower center of gravity over coil springs because the weight of the springs is lower in the chassis. Lower center of gravity is a good thing.

Going to rear coil springs takes all the rear end weight of the car including weight transfer to the rear during acceleration off the spring plate bushings.
If using urethane or rubber spring plate bushings they are very stiff to move because of sticktion and that makes a harsher less controlled ride over bumps and humps in the road no matter what.

Installing Elephant Racing polybronze or Rebel Racing spring plate bushings will eliminate that sticktion and that will make torsion bars ride just as smooth and nice as coil springs because a spring is a spring.

That type of spring plate bushing upgrade also keeps the rear wheel alighnment from changing during hard cornering and acceleration.
