Ok, I have been following a number of suspension threads for a bit and I have a question. Why does it seem like everything is oriented toward progressive rate springs for performance applications?
Progressive rate springs make my head hurt when you try to match linear damping forces to them. To say nothing of roll and pitch calculations as the suspension dynamics change under load, weigh shift, and linear and lateral acceleration.
I am just not seeing how this is a performance advantage in any way as it introduces an unnecessary dynamic variable into a system that cannot account for it. Without being able to match damping forces in real time like some of the active suspension systems, it is clear that the system is going to be over or under damped except for the single point where the progressive spring rate and the damping compression and rebound are matched.
Can someone fill me in on why this is advantageous over a matched linear rate spring and damper setup?
