COILOVERS DS / BC RACING / AUDI A4

BC Racing DS coilovers for Audi A4

BC Racing DS coilovers for Audi A4 are new high-performance suspension units for drivers seeking sportier, more precise and fully adjustable handling. Developed with BC Racing's motorsport expertise, DS suits dynamic driving enthusiasts, occasional track-day users and owners seeking to improve their Audi A4's chassis without entirely sacrificing comfort.

Purpose of the part

Coilovers replace the original dampers and springs to control body movements, grip and ride height. On an Audi A4, they reduce cornering roll, better manage weight transfer under braking and acceleration and provide a lower, more stable stance. DS digressive valve technology particularly improves support at low damping speeds while retaining effective response when the suspension moves rapidly.

Symptoms or consequences of worn or unsuitable suspension

• Imprecise handling or a floaty feeling at high speed.
• Significant body roll in corners and excessive body movement.
• Pronounced dive under braking and loss of stability during changes in cornering load.
• Uneven tyre wear caused by poor suspension control.
• Loss of traction or grip on poor road surfaces or during sporty driving.
• Worn dampers causing reduced comfort and potentially longer braking distances.

Benefits of replacement

• Clear improvement in driving precision and steering feel.
• Reduced body roll, pitch and weight transfer.
• Adjustable ride height to adapt the Audi A4's styling and handling.
• 30-level firmness adjustment to balance comfort, sporty road and circuit use.
• Digressive technology provides excellent body support without making the suspension unnecessarily uncomfortable.
• More consistent operation thanks to a robust monotube design and high-performance oils.
