Fall-Line Motorsports E9X M3 / E82 1M Billet Aluminum Rear Trailing Arm Set

Best of the Best

Fall-Line Motorsports has leveraged over a decade of manufacturing expertise to create an ultra-premium version of the E9X / E82 1M tension and trailing arm.

Unlike the factory's deformation-prone stamped steel arms, Fall-Line’s custom version is precision-engineered from 5-axis CNC machined billet aluminum. These beautifully crafted arms are pocketed to reduce weight without sacrificing rigidity and are finished with a hard coat black anodizing for superior wear resistance. The included hardware is also upgraded, featuring 10.9 grade corrosion-resistant extended bolts to replace the weaker factory versions.

Designed for both street and motorsport use, these arms bring added strength and peace of mind, setting a new standard in the E9X trailing arm market.
