Why a sway bar, heave spring, and wheel springs?

Happy to learn.

So, have we come to the conclusion that having all 3 "springs" is beneficial?
No. We've concluded that individual wheel springs are redundant if you have an ARB and heave spring. You do not need them for tuning or performance purposes. The reason they are used is for things like convenience (easy to change).

Dedicated heave springs are not commonly seen outside racing series with significant downforce. Running roll springs stiff enough to deal with huge downforce limits your ability to tune your system for mechanical grip.
I think Koeinigsegg is the one exception, and they use it in the rear primarily for tuning pitch during launch and as a useful location for putting their ride height gubbins.

Why be more complicated when monoshock front ends running belville washers for roll resistance work in F3? Because it's limiting in tunability. They act like they have infinitely stiff roll bars, the left tracking the right very tightly. Not so fun when putting two wheels on the red and white.
