It’s not really a problem though if the shock becomes to linear for the frame though is it? All you have to do is reduce the air chamber size a bit to give it the ramp up at the end, the increased negative spring size should stay the same shouldn’t it? Giving you a more supple shock in the first few inches of travel.
Besides, if you’re using too much travel with the new shock….just add some more PSI…the new negative spring means that it will keep more small bump compliance at higher PSI ranges….and you will get increased mid stroke support.
Personally if I hadn’t had the shock PUSHed, I’d get that done first though.
