Based on this diagram, with my winter tire/wheel setup:
B=13.75in
A=19in
MR @ wheel=0.72
Strut angle=10deg
MR of strut=0.973
For the rear I calculated:
B=15in
A=27.25in
MR=0.55
This puts my winter setup ride frequencies at:
F=0.93
R=1.35
Adding my race springs, but not accounting for the wider wheels:
F=1.45
R=1.85

Guess what spring rates you need for a true 2.0/2.2hz split?
800/1050
I've been schooled.
The dude abides.
I thought the knuckle and strut move as 1 piece so the motion ratio is determined mainly by the strut angle (the topic is reported widely across the internet with many different diagrams).
I think your suspension analyzer post with an output of 0.93 is likely the most correct.
