What about using a bigger sized shock that already exist ex 8.5 I2I?I think it's a good move.
People who have experience in suspension maintenance and engineering will agree that the room inside the current shocks (especially the 200x57 which is very popular) is very limited, and that makes engineers compromise a lot of things like the length of the shaft bushing, the amount of oil, IFP length, IFP chamber volume, space for adjusters (rebound adjuster on Vector Air and Float X for example), air piston length, air spring volumes and equalization port location etc.
I have spent a lot of time figuring out how to make some shocks perform better or be more reliable and most mods would require more space.
Anyways, hopefully those brands will collaborate together and come up with some shock sizes that won't need any change for at least a decade.
