Remember, spring return rate (speed of return) and spring resistance (in lbs) are two totally different things.

Considering the front whites are off by .22 & the jump from one grade to the next is only .1, I'd call that pretty significant. With that kind of deviation, I would think it would be a good idea to measure & try to match springs.
This is a measure of spring resistance & I understand how it is measured, but how do you measure return rate? would that be a formula involving the spring resistance, density & diameter, among other factors?
