COILOVERS DS / BC RACING / MAZDA MX 5

DS BC Racing coilovers for Mazda MX-5

BC Racing DS coilovers are new high-performance suspension units intended for Mazda MX-5s, developed for drivers seeking more precise, sportier and more consistent handling. Drawing on BC Racing's motorsport experience, these coilovers offer an excellent balance of dynamic road use, sporty driving and occasional track days.

Purpose of the part

A coilover kit replaces the original dampers and springs to control body movement, ride height and chassis response more effectively. On a Mazda MX-5, a lightweight vehicle particularly sensitive to suspension settings, coilovers improve steering precision, stability under cornering load and traction on corner exit.

BC Racing DS technology uses a Double Digressive Valving digressive valve, designed to increase low-speed damping while maintaining good high-speed absorption. This design improves control of roll, pitch and weight transfer without making the car excessively uncomfortable for everyday sporty use.

Symptoms or consequences of worn or unsuitable suspension

• Excessive body roll in corners.
• Loss of front-end precision and a floating sensation.
• Body oscillation during braking, acceleration or changes of direction.
• Uneven tyre wear caused by poor suspension control.
• Lack of stability at high speed or on poor road surfaces.
• Less predictable handling during sporty driving or track use.

Benefits of replacement

• Clear improvement in body control and chassis control.
• Precise ride height adjustment to optimise the vehicle's centre of gravity and appearance.
• 30 levels of damping adjustment to adapt handling to the road, track or driver's preferences.
• Greater stability under braking, in corners and during rapid changes of direction.
• More direct, sportier handling than with worn or overly soft original suspension.
• Comfort maintained through digressive technology, more versatile than excessively firm spring rates.
