I think you will find that the springswill betotally unnecessary (except when empty). With the bike loaded, the rail adds very little unsprung weight (you'd probably add that much in springs)... The bike on the railwill be steady as a rock as the axel (and rail) bounce up and down.. and keep in mind, the front half of the rail is sprungby the bike, so it is only (in effect) the back half that is unsprung))
