How we should choose springs depends on how much grip the tires
produce, because that is what gives the loads the springs will
have to take care of. Generally speaking, the softer suspension
gives more grip and harder provide less grip, speaking strictly
from a spring perspective. The problem with soft springs is that
it is difficult for the suspension to provide the proper camber
over a long wheel travel, and if the geometry is not designed
for the suspension travel in question, the tires will lose grip.
In that case, we lower grip with harder springs, but even
destroy grip with softer springs because of a less suitable
geometry. So the question is how soft srings, we can use before
the wheel geometry is wrong versus how hard springs we must have
to cope with the loads that the tires are capable of producing
(with the right geometry). It is easy to find oneselves ending
up in the catch-22.
So what should we do? I think we should be restrained with spring
changes. If we have lowered the car or that we are experiencing
the suspension bottoms out, as well as if stickier tires is used
it's idea of tougher springs of say 20%. But we can also imagine
to change shock absorbers for some more compression damping and
less rebound damping.
