The G body converging 4 link can have some binding issues but they don`t come into play much in drag race use. If your boxed upper arms have poly bushings in them they will be causing some additional unwanted binding though so adj. aftermarket arms with a spherical bearing at one end like Edelbrock or Currie would be a nice upgrade. The rest of the combination depends largely on what you`ve already got. Spring rates and heights,shock type,ride height (lowered?),both front and rear. Can you give us a little more info? Marcus SC&C
