Maybe of interest, maybe not. In a dual rate spring, like the Front of the KW coilovers, if the spring rate of the shorter tender / helper spring is 200 lb. and the spring rate of the main spring is 200 lb. then the spring rate of the two springs assembled together is (AxB)/(A+B) or 100 lb. until the tender spring is full compressed and then the rate is that of the main spring, 200 lb.

In fact the rate of most tender springs in a dual spring setup is usually less than 120 lb. and their lenght is usually about 2" to 4", so they compress fully very quickly, as will be the case with the KW's where the tender spring will be fully compresed just by the car sitting on the ground.

Just some food for thought.
