As you know I also have the Calmini winch bumper and some day a porta winch (ha). I went with Calmini's t-bar and they have preformed well. I don't think I've had much saging if any. I check the heigh every once in a while. Apparently there are two made by the same company and one claims to be stiffer. If you don't mind the stiffness, you're probably better off with the Nismo since they're also less expense. Next is shocks.
