Tein EDFC Active - Damping Force Controller

EDFC Active - Adjusts damping force instantly according to G-Force & Speed. EDFC ACTIVE makes it possible to adjust damping force with ease from the driver's seat, by controlling stepping motors installed on each shock absorber. Built-In G-Sensor allows G-actuated automatic adjustment of damping force while driving. Additional automatic speed-sensitive damping force adjustment feature is available with the use of optional "GPS kit" (sold separately).
