COILOVERS DS / BC RACING / PROTON PUTRACOUPE M21

Product introduction

BC Racing DS digressive coilovers for Proton Putra Coupe M21 are designed for drivers seeking high-performance, adjustable and reliable suspension. Drawing on BC Racing’s motorsport experience, these new coilovers offer an excellent balance of driving precision, handling and comfort for sports road use and occasional circuit outings.

Purpose of the part

Coilovers replace the original dampers and springs to allow precise adjustment of ride height and suspension behaviour. DS digressive technology, based on a double-digressive-valve piston, improves low-speed body-motion control while maintaining a stable response during rapid changes of direction, heavy braking and hard acceleration.

Symptoms or consequences of worn or unsuitable suspension

• Imprecise handling and lack of cornering stability.
• Excessive body roll during changes in cornering load.
• Significant pitch under braking or acceleration.
• Loss of grip on uneven roads or during sporting driving.
• Uneven tyre wear due to impaired suspension behaviour.
• Floating sensation or lack of control at high speed.

Benefits of replacement

• Clear improvement in driving precision and steering feel.
• Reduced body roll, pitch and weight transfer.

• Improved stability during dynamic driving and occasional trackdays.
• Robust design suited to regular sports use.
