XYZ Racing Racing Spec Coilovers — Mercedes-Benz C CLASS W205 6 CYL (Cancellation Kit for Electronic Damping) 2015-2021

The W205 C-Class arrived with adaptive AIRMATIC or Agility Control damping as standard on the six-cylinder cars, software that constantly second-guesses your inputs the moment you start pushing on a circuit. Racing Spec coilovers replace that logic entirely with fixed-rate mechanical control, and this cancellation-kit variant is built specifically to remove the electronic damping conflict so the car stops fighting itself mid-corner.

For a 3.0-litre C300 or C43-based W205 heading to track and time-attack days, that matters more than outright spring rate. This kit is aimed at drivers who’ve already decided the standard chassis needs a proper circuit-ready foundation, not a compromise setup shared with the school run.

What this coilover does for your 2015-2021 Mercedes Benz C CLASS

Fitted to a 2015-2021 W205, this coilover kit lets you set ride height and damping to suit the car’s actual weight distribution rather than a factory average, sharpening turn-in and cutting the body roll that six-cylinder W205s carry through their nose and rear axle under load. Because the electronic damper cancellation kit removes the factory AIRMATIC/Agility Control control unit from the equation, the suspension responds purely to spring and damper settings you choose, with no software intervention smoothing or delaying the response. That means more consistent weight transfer through direction changes, better front-end bite under trail braking, and a rear axle that stays settled through fast, repeated corners instead of hunting for a damping curve. On a car this heavy, predictable load transfer is what lets you carry more speed into apexes with confidence.

About the Racing Spec coilover

XYZ Racing’s Racing Spec damper was developed directly from circuit racing programmes, with settings drawn from series such as WTCC rather than road-car baselines adapted for track use. For W205 owners running further chassis or drivetrain upgrades, XYZ Racing also offers a bespoke shock absorber service: supply details of your car’s modifications and the circuit you intend to run, and dampers can be built to that specific combination rather than a generic track setting. That approach reflects how this range is positioned, as hardware for cars already built for serious circuit work, not a fast-road compromise. The cancellation kit variant specifically addresses six-cylinder W205s fitted with electronically controlled damping, giving the mechanical coilover full authority over the ride without the factory system trying to override it.

Fitment for the Mercedes Benz C CLASS (2015-2021)

This kit is built for the Mercedes Benz C CLASS W205, six-cylinder variants fitted with electronic damping (chassis code ME07-5-C), covering the 2015 to 2021 production run. The cancellation kit configuration is required specifically because these six-cylinder W205s came from the factory with adaptive damping control that needs to be removed for the mechanical coilover to function correctly.
