S30 Spring Specs
There are many spring options available for the 1970–1978 S30 Z cars. In addition to the common aftermarket choices—such as Eibach and Tokico—you can also use springs from other S30 models.
All S30 springs interchange with no fitment issues. However, swapping springs between different models will cause slight changes in ride height, depending on the combination of your car model and the springs you choose.
