Swave & Summit Rear Trailing Arm Reinforcement Bar for Focus Mk4 (ST-Line)

Enhance the handling and stability of your Ford Focus Mk4 ST-Line with the Swave & Summit Rear Trailing Arm Reinforcement Bar. Developed using proven motorsport engineering, this chassis upgrade delivers the strength and rigidity needed to reduce unwanted body flex and sharpen your car’s overall driving response.

Originally designed for rally and drift competition, Swave & Summit chassis equipment brings race-level precision to the road.
