It is doubtful that Nissan ever manufactured front springs for the
roadsters. It is most likely that they were purchased from a supplier.
The "NEW" springs were made in the USA by a company named Eibach and were
ordered to be functionally equivalent to the ones from Japan. While the
springs are different in appearance they may be functionally the same
within accepted tolerances.
What does "Stiffer" mean with regard to spring design or function? It is
not a term found in the "Handbook of Mechanical Spring Design" published by
Associated Spring of Bristol, Connecticut. Rate, free length, solid height
and deflection are some of the terms found in the book. How do you define
stiffness and how did you measure it? It may be described in a recent
pharmacopoeia related to the characteristics of Viagra?
Have you calculated the rates of the "Original" springs and the rates of
the "New" springs based on a formula that considers mean diameter, wire
diameter, number of active turns and free length among other variables?
All spring design is founded on Hooke's law according to the handbook.
Have you actually measured the rates of the "Original" springs and "New"
springs? Please provide data if you have it on either or both configurations.
