HR bar torsion ?

[turbocamino1]

Trying to figure which of the 4 points take the biggest shock on launch. first thought was the left side, rear upright, gets pushed up..but i keep second guessing myself?

at launch with stock instant center the car tends to squat on right rear which loads the right hiem ends in compression forcing against frame , left hiems loads in extension pulling on the bolts .. axle stays level

usually youll add a 1/2 turn or so to lengthen the passenger and add a slight preload , this is done with driver in seat
