Suspension geometry | Jacking | Instant center & axis | Roll center | Camber gain | Scrub of wheel

Suspension geometry is a broad subject of understanding ,how the unsprung mass of vehicle is connected to sprung mass. Suspension geometry is made for constraining the motion of knuckle in 5 directions with respect to vehicle body. In this video you will learn about the various parameters that are involved the the designing of Suspension geometry.
1) DOF & Kinematics of Suspension geometry
-2) Instant center & Instant Axis
3) Jacking & Roll center

    I've seen lots of these videos but none of them explain what we should want in real terms, ie, I want to use specific hubs or maybe design my own but how do I determine the desired arm length, anti dive/squat, instant center ect. I currently stuck using factory geometry but if I could understand the effects of changes in layman's terms, I could experiment. Your videos help but don't go quite far enough.

    Vatsal - I love the video and the channel. Question for you about the jacking discussion at around 6:20-6:30 of the video. I think the force (Fy) would be multiplied due to the lever distance between the tire's contact patch and the lower spindle-to-control-arm mount point (lower ball joint). If the lower ball joint were moved lower (closer to the contact patch), this would reduce the amount of force F2 that is exerted on the lower ball joint and transferred through the control arm to the body. Let's assume the frame mount of the lower control arm is also moved lower the same amount as the ball joint, so the control arm angle towards the frame does not change. This would reduce the amount of force Fz contributing to jacking. Is that right? Now, let's move the upper spindle-to-control-arm mount point (upper ball joint) higher, resulting in a taller spindle overall. This time, though, we change the angle of the upper arm slightly to keep instant center (IC1) at its current distance from the wheel. Because of the further distance apart of the pickup points, does the force transferred back from IC1 (force F1) effectively have less of a multiplication effect, resulting in reduced jacking forces? It seems that overall, having a taller spindle (longer distance between ball joints) offers numerous benefits in this regard. Appreciate any thoughts.

    Basically Anti-geometries changes the pitch attitude of Car.They apply a moment at instant center due to which the pitching or squatting attitude changes,and accordingly the forces are distributed among the A-arms and Strut.

    How does one use the instant axis to apply it to a real race car... more specifically a dirt late model or modified? These cars have a lot of travel across the rf suspension instant axis. I'm assuming it moves as the car moves, i.e.the rf susp travels into jounce 5 to 6 inches.

    Your explanation of the McPherson suspension is completely wrong. In your 5 links diagram, your uprights will have no rotational stability what so ever. In a McPherson suspension, there is no horisontal rotation axis between the uprights and the lower part of the dampers. What is preventing the wheel from tilting or rotating in your diagram?
