I am not sure about the spring rate of the Yokomo pro spring. but here is the chart for the spring set from soft to hard.
(Soft) Black→Blue→Yellow→Pink→Green→Orange (Hard)
These longer length springs have a more progressive characteristic. Soft initially, the rate becomes progressively stiffer as the chassis goes into roll. As a result, less stress is placed on the tires, allowing the tires to provide better grip for improved lap times. All of the springs are colored white to blend in easier with the surrounding parts. Each spring is color marked to indicate spring rate.
