The FSD works very well with Eibach Pro Kit sprngs. H;ever it is
not coilovers so dunt expect indecent speed cornering handlings.the
FSD is more for street use and comfort. I think it offers beter
value n less ccostly than the KWs ,Bilsteins or ZEAL..etc
U shud not use stock srings wz aftermarker shocks unless specified
by manufacturers, this is because each springs n shocks has their
own rebound damping rating.
