This optional product makes it possible for the driver to control the damping force on Cusco ZERO-2E coilovers by controlling a motor installed in the shock absorber while being seated in the driver's seat. Since the damping force can be manually controlled with ease to meet different situations, the driver can enjoy variations in the suspension setting. Go from living your life a quarter mile at a time to Sunday cruising at a buttons press. Cycle through the 5 steps of dampening in the front and rear of your Cusco coilovers with ease. The compact operation panel (approximately 100mm wide x 30mm tall x 30mm deep) is easy to mount. Brightness and sound levels can be changed to suit your desires.
