Some cars do just have heave springs and an arb. Problem is you have to change both then when you want to change the individual wheel rate so it hurts quick adjustments at the track
Thank you Phillip.
There are only two types of motion of the chassis - either roll or pitch. The anti-roll bar generates a spring force in roll. The heave spring generates a spring force in pitch. The wheel rate is simply a function of those two spring forces.
I guess you are saying that if you have a car with just an ARB and a heave spring, and you want to increase
both the roll stiffness and the heave stiffness at the same time, then you have to change both the anti-roll bar and the heave spring (two springs). Versus, if you had a car with wheel springs, ARB and heave spring, you'd have to change each wheel spring (two springs?).
