I saw this on Wikipaedia: At some point in the platform's lifetime, the term "G-Body Shuffle" became popular in the drag racing community (where the cars were often modified fo r racing) for the vehicle's side-to-side motion of the rear end after takin g off from the starting line. This was due to the car's triangulated four-l ink rear end suspension, which caused uneven torque to the rear wheels unde r strenuous driving.
What is the effect with triangulated 4-link? I would think a panhard rod li ve axle would be worse for the arse end going sideways.
