One of the best suspension write ups I have ever seen.....awesome details!!
I was looking at the CG plated when I came across this thread. I will defiantly will make my own. They obviously did no testing or calculations.
Question for the poster:
Did you account for the CG OEM spring perch deflection under load. I measured about 10 mm for the OEM spring perch. I suspect this came out a wash or close to it.
As for the rear spring compressing on a curved axis. I did a non linear analysis in Ansys and the spring rate does increase anywhere from 15-40%. This is dependent on spring wire diameter, spring length and stroke position so not a straight forward answer. I resolved the issue with the a sealed articulating spring perch placed between the helper spring and main spring. The soft helper spring works well at taking up translation by deforming as well. This made a very noticeable improvement and ride quality was a night a day difference especially over rough roads.
