How to tune your ShermanS / Patton / Lynx suspension 101
I made this general guide because I see a lot of people who didn't tune their suspension for various reasons and also because someone asked me if I couldn't make a proper guide, tuning your suspension can be night and day in how it feels, even if you think it feels good out of factory it can feel even better when tuned and also be better prepared to tackle bigger obstacles.

Lots of spring rate anxiety being shared lately...
But I feel that a 6% change in rate (between 62lb/in to 66lb/in) is a pretty small difference.
Begod aftermarket involves far more dramatic changes: coil springs with rates varying by 30% on the same EUC.
Some example data:
SS here, 62lb/in. Two springs, so total stiffness 124lb/in (2.2kg/mm).
I'm a 165lb riding weight, and let's assume 70lb of the EUC mass is 'sprung'.
By the numbers, the suspension should sag about 1.9" under
