This is a direct replacement for the factory BMW rear shock mount reinforcement, as equipped by BMW on Z3 models. This also fits all E36 and E46 models as well. Turner Motorsport makes our own that are thicker but these can also do a good job of preventing cracks and deformation of the rear shock towers. Priced per reinforcement plate. Order 2 to cover both rear shock towers. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts.
