Mercedes C43 AMG W205 Coilovers (2014–2021) – GT-1

Riaction Sports Coilovers for the Mercedes-Benz C43 AMG W205 AWD are designed to improve handling, reduce body roll, and provide adjustable ride height while maintaining comfort for everyday street driving. Developed for the all-wheel-drive C43 AMG platform, this suspension system provides greater control over chassis movement during cornering, braking, and acceleration while allowing drivers to achieve a lower ride height. Featuring 32 levels of damping adjustment, Riaction Sports Coilovers allow drivers to fine-tune suspension firmness based on road conditions and driving preferences. Full-length ride height adjustment provides flexibility for lowering the C43 AMG while maintaining usable suspension travel, making the system suitable for daily driving and spirited street use. The monotube damper design incorporates a 44mm high-flow CNC 6061 aluminum piston, multi-thickness valving shims, and a low-gas-pressure internal system to provide consistent damping response. Combined with SAE9254 cold-wound springs and 7.5W compounded suspension fluid, these components help manage weight transfer, reduce excessive body movement, and maintain predictable handling through corners and rapid directional changes. Each kit features seamless 52mm electroplated carbon steel shock bodies, CNC-machined aluminum internal components, and polyurethane oil seals for durability and consistent operation. The dampers are fully rebuildable for long-term serviceability, and every Riaction Sports Coilover kit includes a 2-year factory warranty against manufacturing defects.
