I just installed a set of k-sport coilovers and the rear end springs are WAY too stiff... Does anybody know the weight of the rear end on a stock 96 RS? I have about a 3" drop in the rear and I do not know what length and spring rate to put on. I believe the k-sport's came with a 390 spring rate in the rear. I literally need to stretch after a long ride because my back hurts so much.
