EDFC (Electronic Damping Force Controller) makes it possible for the driver to control the damping force 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. This adjustment is connected with the power source for lamps, and it functions when the dimmer function is in operation at night. 8. Mis-operation preventive function The EDFC is equipped with a lock mode, which prevents mis-operation. The 'key' mark is displayed and all operations become impossible including turning the power on and off. It is useful when the driver allows another driver to drive an EDFC-equipped vehicle.
Fits on ONLY Vehicles with Tein EDFC compatible coilovers.
