BC Racing DS-SA coilovers for Renault Megane 4 RS 2016+

This BC Racing DS-SA coilover kit is designed to improve the dynamic behavior of the Renault Megane 4 RS from 2016. Sold by 4, it replaces the original suspension elements with a more efficient adjustable assembly, suitable for sports use on the road, trackdays or chassis preparation.

Thanks to DS degressive technology, these coilovers offer excellent control of body movements, particularly during hard braking, rapid downforce changes and strong acceleration. The spring rating is 6 kg/mm ​​at the front and 5 kg/mm ​​at the rear.

Purpose of the part

Coilovers provide the connection between the chassis and the wheels by controlling suspension movements. They allow you to manage damping, ride height, roll, pitch and mass transfers.

On a Megane 4 RS, a high-performance suspension is essential to maintain traction, steering precision and stability at high speed. The BC Racing DS-SA coilovers allow the behavior of the vehicle to be adapted according to the desired use, from a sporty road setting to a firmer circuit configuration.

• Deteriorated handling and insufficient cornering precision
• Excessive body roll during changes in cornering load
• Pronounced nose dive under braking and squat under acceleration
• Loss of traction on uneven roads
• Uneven tyre wear
• A floating sensation or instability at high speed
• Tired shock absorbers causing reduced comfort and safety

Benefits of replacement

• Clear improvement in handling and front axle precision
