E30 (Z3/E36TI/E21) REAR TRAILING ARM SPHERICAL BEARING SET

**Please note these are currently being redesigned, they are available for purchase but we are waiting for an estimated ship date by the manufacturer** Our E30 (Z3) Spherical Bearing Set was created to aid in delivering smooth suspension actuation, as well as remove unwanted linkage compliance. These bearings are especially important when running an adjustable rear subframe (i.e. eccentric adjusters). Introducing misalignment into the rear trailing arm can cause binding and pre-mature wear on other types of non-spherical bushings. The spherical inserts allow misalignment while retaining smooth and consistent oscillation of the trailing arms. This spherical bearing set will work with any BMW cross models that share the rear trailing arm bushing with the E30 chassis (i.e. Z3/E36TI/E21, etc.) Construction: Both the Bearing Sleeves and the Spacer Inserts are machined from billet chromoly steel. The Spherical Bearings are a Heat-Treated PTFE lined unit specified specifically for motorsport
