COILOVERS DS / BC RACING / BMW Z3

BC Racing DS coilovers for BMW Z3

BC Racing DS coilovers are designed to improve the BMW Z3’s dynamic handling during sporting road driving and occasional circuit outings. Drawing on BC Racing’s motorsport experience, these adjustable dampers offer an excellent balance between precision, effectiveness and comfort in use.

A new BC Racing product, this DS coilover kit allows fine adjustment of ride height and damping firmness to adapt the chassis to your driving style. Spring rates are always stated in this order: Front / Rear.

Part function

Coilovers replace the original dampers and springs to control body movements more effectively. They act on roll in corners, pitch under braking, weight transfer under acceleration and the vehicle’s overall stability.

The DS range uses digressive valve technology, called Double Digressive Valving, which increases damping at low suspension movement speeds for better chassis control while retaining a stable, progressive response at high suspension movement speeds. This design provides more precise steering, better feedback under cornering loads and optimised traction.

Symptoms or consequences of worn or unsuitable suspension

• Reduced road holding and lack of precision during sporting driving.
• Excessive body roll in corners and instability during changes in cornering load.
• Substantial dive under braking and front-end lift under acceleration.
• Loss of grip on bumpy roads or during prolonged cornering loads.
• Uneven tyre wear due to insufficient control of suspension movements.
• Floating or bouncing sensation due to worn dampers.

Benefits of replacement

• Clear improvement in driving precision and chassis feel.
• Reduced body roll, pitch and weight transfer.
• Height adjustment allowing the vehicle’s centre of gravity to be lowered.
• 30-level firmness adjustment to adapt handling to road, circuit or sporting daily use.
• Better stability under heavy braking and through rapid sequences of corners.
• Sportier appearance thanks to adjustable ride height.
• Effective, reliable solution to optimise a BMW Z3 without excessive compromise on comfort.
