BMW E9x 330xi ECS Rear Trailing Arms

While the BMW E9X 330xi is capable of sustained, high-performance driving, its suspension system is not without flaws.

Specifically, the rear trailing arm fitted to these models has a tendency to fail without symptoms, potentially leaving you stranded without a critical suspension component.

ECS has solved this issue with a meticulously engineered Performance Rear Trailing Arm, made from aluminum & better designed to withstand the demands placed on it.

Not only is the unit more robust & dependable than the factory unit, it's also lighter, reducing unsprung weight.
