Two reliable sources have told me they don't think the M3 differential bushings will reduce deflection very much v. oe and both suggest Powerflex poly bushes. Two other forum members who have the delrin differential bushings say NVH barely increased v. two members who have Powerflex poly bushes, who both note an increase in NVH. Would love to hear from anyone who's swapped in the M3 diff bushes, even though it appears some M3 owners are swapping their diff bushings out for aftermarket and don't have the torque of a tuned 335i.
