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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eBMW 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eGaragistic spherical RTABs are engineered specifically for high-performance applications where precision and durability matter.
