COILOVERS DS / BC RACING / BMW 4 SERIES

BC Racing DS coilovers for BMW 4 Series

BC Racing DS coilovers are new high-performance suspension systems intended for the BMW 4 Series. Developed for drivers seeking more precise handling, improved body support and adjustable ride height, they are an ideal solution for performance road use and occasional circuit outings.

Purpose of the part

Coilovers replace the original dampers and springs to control suspension movement, vehicle attitude and contact with the road. DS digressive valve technology provides firm, responsive low-speed damping to limit roll, pitch and weight transfer while maintaining good stability during rapid suspension movement.

Symptoms or consequences of worn or unsuitable suspension

• Excessive body roll in corners.
• Lack of front-end precision and a floating sensation.
• Loss of grip under braking, acceleration or changes in lateral load.
• Uneven tyre wear linked to poor wheel alignment or deteriorating damping.
• Less stable handling at high speed or on poor roads.

Benefits of replacement

• Clear improvement in road holding and driving feel.
• Reduced body roll and better control of weight transfer.
• Precise ride height adjustment to optimise appearance and handling.
• Damping adjustable through 30 levels to adapt the suspension to the road, circuit or driver's preferences.
