The black bushings were only ever to special order and have never been made for the X5. The only black bushings I have ever seen are on multiple piece bushes like those on parts with a rotational element like lower arm or trailing arm bushes where the housing is in black and the rotational part is purple.

Production IS NOT expected for at least another 5-6 weeks and full production much further ahead. There are no plans for any other thrust arm bushing other than the purple ones and the yellow for the subframe.

The Superpro bushes are also 3x the cost of the Powerflex.
