You are basically making a progressive spring. This is offered by a couple of different companies. I am not sure where to get these springs other than at A Main hobbies. That has been the only place I have seen them at the present.
My shocks absorbers extends to the fullest, can it do the same without retracting when it's at rest? everybody is having droops in their lifetime. just want to try something new this time, and maybe later on i would reduce my hard or short shock spring to attain or get a droop back. It depends when it's really needed.
I JUST HOPE THEY WOULD GATHER SCIENTIFIC DATA ON MY SHOCKS TOO, who knows i could get a better PERFORMANCE DATA than theirs hehe. i just hope i could help to those who have little penny to draw from their pocket. or instead spend their money to an aircraft grade aluminum parts. cheers fellas. i feel some kinda robin hood.
Oh about the alignment, the adjustable collar will do the job, you could use 4 pcs for each (maybe held back to back), i just use two. i think two is enough.
