After development and testing on our own SPEC-E30, we’re happy to now offer the Garagistic E30/Z3 Rear Trailing Arm Spherical Bearing Bushings. Designed as a direct replacement for the factory rear trailing arm bushings (RTABs) found on the BMW E30, E36 318ti, and Z3 (OEM Part Numbers: 33329061945, 33321137564), these spherical bearing bushings eliminate the excessive deflection found in the factory rubber bushings for significantly improved rear suspension precision and consistency.
