I ain't done it yet but I believe its pretty simple, Fronts, remove wheel and undo the 2 bolts which hold the damper to the pivot hub, unclip brake hose. Remove cap in engine bay, remove nut using an allen key to hold strut in position, remove all washers and rubbers from engine bay and remove suspension from car. refit all rubbers to coilover and put back in car, refit two bolts at swivel hub, using new nuts, refit rubbers and washers in engine bay and refit nut. Refit wheel. Rears is pretty much the same, only there is inly one bolt at the base of the strut. refit all washers and rubbers
