This is correct.

To add to above, the spring rate is stated as the force generated per unit of compression. Ex: 1,000 Lbf/Inch, 1,700 N/cm etc.


Also, its spring FORCE, not pressure. Spring pressure is a common misnomer racers seem to always use, and it just wont die. Its entirely wrong. Its not a pressure, Its a force.
