What kind of "play" do you feel in the pillow ball? Might still be usable. You can prob get the parts you need to fix that for relatively cheap.
But just a side note. I have had ISCs on 3 diff cars and loved them. I had the street comfort on my first LGT then the Street Sports on my old WRX and now another set on my current LGT. They ride great. Yes they are stiff but thats what you have to expect when getting coilovers. you just have to play around with the preload and dampening to get what works for you. My car is back on the KYBs and Cobb springs for winter. If I still have the car by spring the ISCs will be going back on.
