Just some light thoughts here over that it is said that the rear suspension of a Rover 75/ZT is from a BMW E46, and so whether we should modify Rover 75 rear arms to be that of the E46? In case they last longer because the E46 rear arms may look stronger? I paint my rear arms with black Hammerite and that made a rusty second hand pair (that cost me £50 for the pair) I had fitted in 2019 have lasted very well indeed. They still look very strong with no rust in sight.
