   Just wondered what the different size torsion bars actually do.

   Larger diameter = stiffer.

   Oh right is that all. How different will the back end feel.

   When fitting a suspension kit to a car with rear torsion bars, as the spring rate goes up, you will dial in understeer.
   
   The torsion bar is a stretched out spring.
   You want to do the same to the rear as the front to keep the handling balance, a thicker torsion bar gives a higher spring rate.
   The trick is to match the front and rear to get the handling you want...
