I have been curious about this as well
For instance, yesterday someone suggested negative front toe to improve steering and counter under steer
It worked but braking suffered,
Another trick l have had success with is buying both hard and soft race suspension setups, just to get the recommended spring rates, then using them to set the adjustable suspension, hard works well with race tires, and soft works with sport tires, while stock works for comfort tires
sway bars should be set softer when using stiff springs, and firmer when using soft springs,
the sway bar settings should be set after the springs, and opposite the spring settings,
A word of caution!!! Do not change from one suspension type to another while making adjustments! It will reset all your work when you return to the adjustable setup,
I use the far right 3rd setup to check spring rates, as l usually only have a race tire and a sport tire setup in the first two slots, and use the last 3rd one as a throwaway for testing changes,
Mid engine cars can be improved by adding ballast till you get 50/50 front/rear weight balance
For ride height l start at minimum setting on the adjustable suspension plus 20, so if minimum ride height is say 75 l set it at 95, that usually is 10 below the default setting with the adjustable suspension,
I am now starting at 10 above minimum ride height as a general rule,
