E30/Z3 Rear Trailing Arm Spherical Bearing Bushing (RTAB)

Overview

It's time to upgrade your rear suspension with 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.

BMW designed the original RTABs to prioritize comfort, noise isolation, and ride quality. While great for daily driving, the soft rubber allows the rear trailing arms to move under load, resulting in unwanted toe changes and the "floating" or unstable feeling many drivers experience during aggressive cornering, drifting, or track use.

Garagistic spherical RTABs are engineered specifically for high-performance applications where precision and durability matter. Each set is precision machined from high-strength 7075 aluminum and paired with stainless steel spacers for exceptional durability and corrosion resistance.

Whether you're building a dedicated drift car, autocross car, or road race car, these bushings provide a solid, repeatable suspension pivot that keeps your rear alignment consistent under the most demanding conditions.

Unlike many spherical bearing solutions, our design features a serviceable and replaceable bearing. When the bearing eventually wears out after years of abuse, it can be replaced without removing the aluminum housing from the trailing arm, making maintenance quick and inexpensive.

Please Note: These will transmit additional noise, vibration, and harshness, and are best for race applications only.
