Calculating/measuring Fork Spring Rates

[HispanicSlammer]

Can make coil springs heavier rate by using larger wire or more coils.......progressive rates (heavier the more they're compressed) are achieved by tighter wound coils on one end....................... :thumbsup:

Progressive rate springs use the same wire, wound tighter at one end. This design is to intentionally bind up the tighter windings and increase the spring rate by reducing the effective number of coils availible to compress. The tighter wind does not impart any strength or weakness to the spring just less space before they bind up - its the effective number of windings that cause your spring rate to increase. Once a spring binds up on the tighter portion there the less tighter wound coils are still able to compress but less of them so the spring rate goes up, if the tighter wound springs are all of the same spacing then the looser wound coils then its a two rate spring, if the tighter wound springs gradually get tighter then its a true progressive rate spring, up to the point where they bind up and cant move.

Can anyone tell me if you have successfully mesaured....cut.....measured again.....installed......... and confirmed that this is doable, corrects sag numbers, and handles well?
