COILOVERS DS / BC RACING / PROTON WAJA

BC Racing DS coilovers for Proton Waja

This BC Racing DS coilover kit improves the Proton Waja's dynamic handling for sporty road and occasional circuit use. Supplied new, it draws on BC Racing's motorsport expertise and advanced digressive damping technology to balance precision, traction, comfort and effectiveness.

Purpose of the part

Coilovers replace the original suspension components for precise ride height and damping behaviour adjustment. They are essential to tyre contact with the road, weight transfer control, reduced cornering roll and improved stability under braking and acceleration.

BC Racing DS uses digressive valve technology called Double Digressive Valving. This provides stronger damping at low movement speeds to better control roll, pitch and body movements, retaining stable response at high movement speeds during rapid changes in cornering load or technical sequences.

Symptoms or consequences of worn or unsuitable suspension

• Imprecise handling and lack of cornering stability.
• Excessive body roll during changes in cornering load.
• Pronounced dive under braking or front-end lift under acceleration.
• Loss of traction on uneven surfaces.
• Premature or uneven tyre wear.
• Floating sensation at high speed.
• Reduced comfort or unwanted noises from worn dampers.

Benefits of replacement

• Clear improvement in driving precision and steering feel.
• Reduced body movements for sportier, more controlled driving.
• Ride height adjustment to optimise appearance and centre of gravity.
• 30-level damping adjustment via a single knob acting on rebound and compression.
• Better stability under heavy braking and through corners.
• Sharper handling than original suspension or a conventional linear valve.
• Adaptation possible between sporting road use and occasional circuit outings.
