In North America as far as I've ever seen the spring rate is measured in pounds per inch (lb/in), that is a one inch depression of the spring will be able to resist a specific weight. So, a 180lb/in spring will be able to support 180lbs when depressed one inch, 360lbs for 2 inches of compression, etc. Some springs are wound in such a way that they are progressive, so the more they are compressed the more they actually resist being compressed, but those don't seem to be as commonly used as the one to one lb/in measurement.

Sway bars don't affect the spring rate if both sides are compressed together, but if one is compressed more than the other, the additional spring rate of the torsion bar can be added to that of the actual spring.

Ok now I understand what you were asking. Our standard spring rate is 250lbs. However we can go higher or lower as needed for different car weights and applications. We can also change shock valving to suit a certain use.
