The shocks fit 1990-1999 model (australian or japanese). The shocks are 20 rate adjustable for bump and rebound (together) adjusted from the bottom (can be adjusted on car). I believe that they are a 40mm monotube shock.
I'm not sure the brand of the springs. They sit approximately 3mm lower than 1995 JDM springs so about an inch lower than 1990-1993 springs I believe.
I was initially selling them as I was going to turn my car into a track car and get a set of ultra stiff coilovers but now I'm saving up to go on holidays instead.
