Ed, The spacers are not part of the stack. They are on top of it and add to the height and subtract from the travel. I will have to agree that the springs will probably not compress as much as the donuts, even new ones, when the weight is on the gear. But I would have to see it to believe it would be enough. It was not in my case. Are you going to make it to the Nationals and/or OSH?
