Really ??? Well this seat can be done, and not raise it anything at all. I asked them to raise the seat from the OEM height...to a specific height, for me. In doing so, they actually cut away 100 % of the OEM foam, all the way down to the seat pan (in the riders' area), and built it up from there. They are able to do the same thing, build the Russell suspension system onto the seat, and keep it at the OEM height.
( there was a joke that went with this post, but even I deemed it to be just plain stupid)
