== Z31 Front Control Arm Replacement and Bushing Upgrade ==

Want to firm up the front suspension and get rid of those rubber bushings? You can easily upgrade to polyurethane bushings, which are available through many aftermarket suppliers.

There are other changes you can do while working with front control arms, as there were two versions of the front control arms. The 1987-1989 300ZX models came from the factory with longer front control arms, adding an extra 10mm for a wider track width. You can use this extra width on earlier models (1984-1986) to add about -5 degrees of negative camber to the wheels, helping with turn-in grip.

You can also achieve the same by swapping the early strut housing for the later 87-89 models and gain camber this way—without the expense of camber plates. Below is a picture of the early (top) control arm versus the late (bottom) control arm:
