hey, its a fairly easy process, undo the bolt on the bottom of the strut and then undo the top two bolts at top of strut, then simply slide old strut out and new strut in. and if your planning on putting stock r32 gtr struts into a r32 gtst its not going to fit anyway as they have different bottoms. if you need a price on some new coilovers for either a set or a pair contact me via my website below
thanks,ryan
