I am contemplating putting coil-overs on my 83'. I was wondering if anyone has any experience using the Ground Control setup? They have a system for the 4000 that I am pretty sure will work. I am just not sure if the spring rates will differ. I am looking for something that will be OK for track days, but not be to stiff on the street. I have some Boge Turbogas shocks that I put in two years ago, but I am not sure if they will be stiff enough if I go to a stiffer spring. GC seems to have a different # for the Bose and Bilstein compatible units. Any thoughts? Thanks

I bought some for mine. Have to wait till my koni adj's are modified to put them on though.

He built some for his Erk using some OEM CQ parts, I believe, which might fit the bill nicely for you. I plan to do this at some point. He tracks his car a lot as well.

I've got the 2Bennett "coil program" suspension which uses Ground Control's collars and springs. I got to pick my spring rates and had Bilstien custom valve shocks for me. It ended up very firm with 325/375 f/r which rocks on track and rots on streets.
