No, not referring to the preload. When I input the weights and angles for my car using a 6.3" travel shock and a 12" spring, performance mode recommends a 150# spring with .47 preload. Then when I input the same numbers but change to a 4.1" travel shock with a 10" spring, performance mode recommends a 200# spring with .52 preload. I don't understand why when changing spring lengths, the spring rate needs to change.
