COILOVERS BR-RS / BC RACING / INFINITI QX70

BC Racing BR-RS coilovers for Infiniti QX70

This BC Racing BR-RS coilover kit is a new suspension solution designed to improve your Infiniti QX70’s dynamic behaviour. Drawing on BC Racing’s motorsport experience, these coilovers offer an excellent balance between performance, driving precision and versatility for sporting road use or occasional track days.

Part function

The coilovers replace the original suspension components to allow precise adjustment of ride height and damping firmness. They control body movements, optimise tyre contact with the road and improve vehicle stability under acceleration, braking and cornering loads.

The BR-RS version has rubber-bushed front and rear top mounts, offering an ideal balance between comfort and dynamic effectiveness. Height is adjusted via the damper’s lower mount without changing spring preload or reducing usable travel.

Symptoms or consequences of worn or unsuitable suspension

• Reduced road holding and a lack of precision in corners
• Excessive body roll when changing direction
• Significant dive under braking or front-end lift under acceleration
• Uneven tyre wear due to poor control of body movements
