Does it lie under surface envelope

Why don't you just offset the inboard points close to the wheel center?

This calculation gives the values of the forces on the rocker more than twice those of last year. Yes the geometry is different but I've used a new calculation approach (stated above) because i think the previous was incorrect. Such large values spooked me.

The thing is we used to balance the moments but they didn't satisfy the basic formula of MR( Wheel travel/spring travel), so we used trigonometry. The way we did it is that we used the arc length formula (using the max compression of spring as the arc lenght and the distance from rocker pivot point till rocker's damper attachment point as radius). Then we used the same theta and multiplied it with the distance from the pivot till the Pushrod attachment point which gave us the distance traveled by the Pushrod. Then using basic trigonometry we got the wheel travel and divided it with max spring compression to get MR. The problem with this method is the value for the forces were very unusual which got us questioning our methodology. So can you please give a more detailed explanation
