I asked this on the other wishbone bush thread so I'll put it here too:

An intriguing facet of this (to me anyway), is why does Xpart/Rimmer list a different Part Number for the Rover 75 rear bush and the MG ZT version? It's always been my understanding that different Part Numbers mean different parts. Yet from what I see, most aftermarket sellers offer the same part for the 75 and the ZT. I assumed it may be to provide the different suspension specs (eg the front camber angles, which through some mechanism are different). But, the reasoning I was given on the forum, is that the rubber used for the bushes is different in its stiffness. A bit like the diesel's lower engine mount bush, which is stiffer than the others. Anyone have a view on this?
