If your E30 is making serious power, your differential is seeing serious loads. That's where the E30 dual mount conversion comes in. An absolute must for V8 swaps. By adding a second mounting point you are effectively spreading the load your stock diff mount and bushing would see. There is a reason that BMW switched to dual mounts on the later models. This conversion was also done in higher powered cars by Hartge. This will not fit E36ti models or Z3 models. Installation is simple. 6 bolts are all it takes (all hardware is supplied). Simply unbolt the two bolts on your diff cover and bolt ours up. Drill four holes into the trunk and bolt it up. That's it!! Comes with chassis mounting points. This will only work with medium case differentials. It will not work with early model small differentials.
