The problem with BMR's bushing is that it is too thin and is just meant to be a hinge point thats it. It really doesnt allow the axle to articulate in the arch that it suppsoed to for everyday driving. Where as Spohn uses a bigger poly bushing that allows for more flex for the everyday stuff.
Or ya can go with what I have the Poly/Rod lca's.. The quietness of poly but has most of the performance of rod ends.
