ECS Performance Adjustable Coilover System - W204 RWD

Transform your W204 C-Class with a coilover system designed specifically with the daily driver in mind. The ECS Tuning Performance Coilover System bridges the gap between performance, comfort, and stance, delivering a sport-tuned setup that feels firm yet compliant on the street.

The ECS Tuning Performance Coilover System delivers a fully customizable, sport-tuned suspension setup engineered to replace your worn factory components with track-tested control and an aggressive stance. Utilizing heavy-duty, zinc-coated monotube shocks and powder-coated progressive springs, this system lowers your vehicle's center of gravity by 0.25" to 2.25" while offering 32 levels of precise rebound damping adjustment to eliminate body roll and maximize grip. Featuring independent body height adjustment, our system allows the shock to operate in its ideal valving range without sacrificing spring preload—plus durable anodized billet aluminum hardware and integrated dust boots, it yields the ultimate balance of longevity, fine-tuned handling, and perfect ride height.
