BC Racing DS coilovers for BMW X4

BC Racing DS coilovers for BMW X4 are new sporting suspension designed to improve the vehicle’s dynamic handling while retaining excellent versatility for sporting road use or occasional circuit outings. Drawing on BC Racing’s motorsport expertise, these coilovers offer precise ride height and damping adjustment to adapt the chassis to your driving style.

Part function

Coilovers replace the original dampers and springs to optimise road contact. Their role is to control body movements, limit body roll in corners, reduce pitch under braking and acceleration, and improve overall vehicle stability. The DS range uses digressive valve technology providing firmer damping at low suspension movement speeds while retaining good absorption of road irregularities.

Symptoms or consequences of worn or unsuitable suspension

• Less precise handling and a floating sensation at high speed.
• Substantial body roll in corners and poorly controlled weight transfer.
• Longer braking distances due to poor control of load on the tyres.
• Uneven tyre wear linked to impaired alignment or damping.
• Loss of traction under hard acceleration or rapid changes in cornering load.
• Reduced comfort with excessive bouncing or imprecise chassis reactions.

Benefits of replacement

• Clear improvement in driving precision and steering feel.
• Reduced body roll, pitch and unwanted body movements.
• Height adjustment independent of spring preload to maintain effective suspension travel.
• 30 levels of rebound and compression adjustment via a single knob.
• Double Digressive Valving technology offering an excellent balance between performance, stability and comfort.
• More sporting and consistent handling in dynamic road driving and on occasional trackdays.
• Scope to adjust the chassis to suit the use, tyres and driver’s preferences.
