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.
jus my 2cts.
