COILOVERS DS / BC RACING / PORSCHE CAYMAN/BOXTER 987

BC Racing DS coilovers for Porsche Cayman / Boxster 987

DS BC Racing digressive coilovers for Porsche Cayman and Boxster 987 provide more precise, sporting, fully adjustable handling. Developed from BC Racing’s motorsport experience, this range balances performance, comfort and effectiveness for dynamic roads or occasional trackdays.

Purpose of the part

Coilovers replace original dampers and springs to control body movement, grip and height. On Porsche Cayman or Boxster 987 they improve roll, pitch and weight-transfer control while precisely adjusting stance for intended use.

DS uses digressive valves, also called Double Digressive Valving. This increases low-speed damping to stabilise the body while retaining effective high-speed response during rapid load changes, hard braking or rough-road passages.

Symptoms or consequences of worn or unsuitable suspension

• Excessive body roll in corners.
• Lack of front or rear running-gear precision.
• Unstable under hard braking or acceleration.
• Loss of grip on uneven roads or during sporting driving.
• Worn dampers causing bouncing, floating or longer braking distances.
• Height unsuitable for sporting or styling use.

Benefits of replacement

• Clear improvement in road handling and driving precision.
• Reduced body roll, pitch and unwanted body movements.
• Height adjustment independent of spring preload.
• Damping firmness adaptable for roads, sporting driving or recreational track use.
• Better chassis feel and more direct response during load changes.
• Good comfort retained through digressive valve technology.
