Since no one has answered this question, i'll give it a shot with what i use. i use 240 lbs seat pressure and change them out when they get down too 220 lbs. The one thing i question though is the 1.805 installed height. You're looking at .630 lift and most roller springs coil bind at 1.180, that leaves no room at all. I have 2 rollers 1 @ .625 lift and the other @ .668 lift and i have the spring heigth set @ 1.950 with .100 long valves.
