3-Way Damping Adjustment
Independent control of rebound, low-speed compression and high-speed compression allows each circuit to be tuned without affecting the others. Low-speed compression controls body movement under driven loads. High-speed compression controls the response to sharp, abrupt inputs such as kerbs and surface changes. Rebound controls suspension extension after compression — critical for weight transfer management and traction on corner exit.
