I have a full set of S13 JIC Coilovers
They came off my 1990 240sx which has a open diff so i do not believe they have been used for drifting.
Also the front end of my car was 2-3 inches off the ground and has no major damage on it so i do not believe they have been taken over any large bumps or potholes.
They all appear to me in perfect shape to me, none of the struts seem to be blown and there is no damage to them.
I believe the model number is SF-1 coilovers althought i could be wrond. They only appear to be height adjustable and not dampening. The fronts have camber plates.
If this price seems to high, PM me a offer that you think is reasonable
