Let's remember that Golfs and Jettas have different weight distributions. Let's remember that most of us are running different tires. Let's also remember that we're all running slightly different suspension setups.
All these things affect the handling, and therefore different bars/shocks/camber settings, etc will give different results to different people. For example, I run stock swaybars, and I can get the tail out on my car pretty easily. Others can't.
