Very simple Assetto terms of how to tune out bouncing. To be technical: Damping (yes I pronounce it wrong like 29 times) or dampers is a hydraulic system (in this case in the coilover’s bottom bit) that generates a force proportional to the rate of change of displacement. Think in scientific terms: Newton’s Second Law of Motion and a real world example of harmonic motion. There’s a more technical term of what dampers are. They not only control the energy transfer to the spring but how it is rele
