Compression damping sets how quickly the suspension moves in; rebound sets how quickly it extends again. The dampers work with external reservoirs, mounted remotely. The struts are inverted, which AST use because that design copes with heavy sideways loads and with braking. Where the car needs them, camber-adjustable front and solid rear top mounts are included.
