BMW E8X/E9X Rear Trailing Arm

The FDF RaceShop BMW Adjustable Rear Trailing Arms are engineered for serious performance on the BMW E90, E92, and E82 chassis, designed for racers who demand precision, durability, and adjustability on and off the track.

Built from high-strength alloy steel, these arms are far stronger than factory components, eliminating flex and deformation when pushing limits through curbing, bumps, or off-track excursions. Each arm features our proven shim adjustment system, allowing precise and repeatable alignment changes without removing the arm — a key advantage for competitive setups where every millimeter matters.

Like all FDF components, these trailing arms are designed to balance strength, serviceability, and weight optimization, ensuring consistent performance in the harshest motorsport conditions. Heavy-duty hardware and spherical bearings are included for a complete, bolt-on installation.
