The Tein EDFC (Electronic Damping Force Controller) makes it possible for the driver to control the damping force on the coilovers while sitting & driving the car. The EDFC accomplishes this by adjusting a motor installed in the shock absorber. Since the damping force can be manually controlled with ease to meet different situations, the driver can enjoy variations in the suspension setting from the comfort of the driver's cabin.

The EDFC is designed to work with Tein's Flex and Super Street coilovers. Even though people have successfully used the EDFC with other kits such as the HA's, we can not guarantee its functionality except with the Flex and Super Street models.

The kit includes the Controller Kit (EDK04-K4469) and the M12-M12 Motor Kit (EDK05-12120).
