My understanding of coil springs is that (as an example) a 300# spring will compress 1" with 300# on it, 2" with 600# on it, 3" with 900# on it, etc. regardless of the length of the spring.
I see from the calculator that going to a longer spring requires a lighter weight spring. I don't understand.
