BC Racing BR-RA/RS coilovers for Renault Clio 4 RS and Trophy

This BC Racing Club Sport BR coilover kit is intended for the Renault Clio 4 RS and Clio 4 RS Trophy. Sold as a set of 4, it replaces the entire original suspension with an adjustable, high-performance solution suited to sporty road driving and track days.

Developed from BC Racing's motorsport experience, the BR range offers an excellent balance of handling precision, endurance and versatility. The BR-RS version is available with 6/6 kg/mm spring rates and the BR-RA with 6/6 or 7/8.5 kg/mm, expressed as Front / Rear.

Purpose of the part

Coilovers provide damping, body control and control of suspension movement. They directly influence stability, traction, braking, cornering behaviour and steering feel.

Their threaded bodies allow these BC Racing coilovers to adjust ride height via the lower mount, without altering spring preload or unnecessarily reducing travel. This design ensures precise, consistent adjustment for both everyday driving and sporty use.

Symptoms or consequences of worn or unsuitable suspension

• Reduced road holding, particularly under cornering load or during rapid changes of direction
• Excessive body oscillation under braking, acceleration or on bumpy roads
• Loss of front-end precision and less communicative steering
• Uneven tyre wear caused by poor control of suspension movement
• Lack of stability at high speed or during intensive track use
• Reduced comfort and effectiveness with worn original dampers or dampers unsuited to sporty use

Benefits of replacement

• Clear improvement in handling precision and dynamic behaviour
• Ride-height adjustment to adapt the vehicle's stance to the intended use
• 30-position damping adjustment acting simultaneously on rebound and compression
• Better body control during sporty driving, hard braking and cornering
• Versatile solution for sporty road use, track days and chassis preparation
• Monotube design promoting consistent damping and resistance to heat build-up
