My idea behind the tender was the length and stiffness. A helper spring is primarily there to keep the main spring in contact with the topmount. The main spring still absorbs nearly all of the weight of the body and results in less total stroke. My thought / assumption is that the tender spring will absorb the majority of the body weight and leave more stroke and suspension travel to the main spring. If the tender is completely compressed at static weight, then the majority of compression travel of the suspension is simply the linear rate of the main spring.

But that is if my assumptions are correct. Maybe the tender is going to function way different than I expect and I do end up with a progressive rate. I suppose that isn't too bad for the daily driver, but it isn't what I want for racing.
