This optional product 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. Go from living your life a quarter mile at a time to Sunday cruising at a buttons press. The EDFC can control the 16 different stiffness settings and can also be put into 32 setting mode which adjusts in half-step increments for the purists and control freaks. The compact (approximately 3.5" wide x 1" tall x 4" deep) control box is easy to mount, making it a great add-on.
