I struggled to find info on this also, back in the day it was all HKS DRag everyone talked about. With them now obsolete these days, a mate of mine sourced KSPort coilovers from MVP motorsports in USA with HKS spec internals for his supra. He never ended up running the car.. I ended up following suit with Myr32 gtr and had them build me a set, my car is only just running now and should be home mid january, in time for some testing then hit the track. Mine is full weight GTR with 3.2 nitto/hollinger setup. What you running?
Will let you know how it goes..
