i might get my hands on a domain with a blown cartridge. it is 180mm travel and i need it to be 160mm at most. I would really like to get the internals to make it a u-turn. My question is if it is possible to reduce the spring 180mm to 160mm and if it is possible to get the leg internals to make it u-turn. Also if i am forgetting anything that would be a problem, let me know.
