Ideal Geometry

[pro-tour79]

From what I get from the question " ideal geometry" is specific settings, the sheet metal around the chassis does not matter, but what does matter is weight, weight bias, CG, wheel base and track width, roll axis, and all of this in turn affects the settings, and driver feel, and spring, and sway bar rates.
but some items can be answered with "as little as possible" such as roll center migration, bump steer.
It is important to keep all that in mind.
