Fall-Line Motorsports Billet Aluminum Rear Trailing Arm Set - BMW E9X M3 / E82 1M
The factory rear trailing arms on an E9X M3 are stamped steel, and under hard track loads they can deform. The Fall-Line Motorsports Billet Aluminum Rear Trailing Arm Set replaces them with solid billet arms that keep their shape lap after lap.
It is an easy install, and no new alignment is required.
5-Axis CNC Billet Construction
Each arm is 5-axis CNC machined from billet aluminum, pocketed to save weight while staying stiff, and hard coat black anodized to resist wear. Upgraded 10.9-grade corrosion-resistant extended bolts replace the factory hardware. Pair with the inner and outer tension arm bearings. Made in the USA.
