Using bump stops to increase the spring rate to keep the car off the ground with aero loading,
Dampers are typically linear or digressive.
When the bump stops are on the shaft of the damper with coilover, the spring rate rises exponentially,
This leads to a decreasing damping ratio and an under damped range on the end of suspension travel (or over damped on beginning of travel). Since I haven't seen a damper that has different damping at different stroke positions.
With rising rate from rocker design the spring and shock stay matched. But not on my car.
Some cars use rubber bumpers as a third spring without damper.
I'm looking at a wheel rate going from 400 lb/in to 700 lb/in. from ride height to full bump.
Is this a noticeable effect?
