XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz C CLASS W204/S204 8 CYL (Cancellation Kit for Electronic Damping) 2007-2014

The W204/S204’s factory adaptive damping was calibrated for a fast road car with occasional track pretensions, not for sustained abuse over broken tarmac stage surfaces. Because this V8 AMG platform left the factory with Mercedes-Benz’s own electronic damper control fitted, XYZ Racing supplies the Tarmac Rally coilover here with the cancellation kit needed to take that system out of the circuit and hand full control to a fixed mechanical damper.

Tarmac Rally is XYZ’s stage-specific spec, distinct from the firmer, single-purpose Top Sport line built around consistent circuit laps. It’s tuned to absorb compressions, crests and mid-corner ruts at speed without the damper losing composure, then do it again a few hundred metres later on the next section of stage.

What this coilover does for your 2007-2014 Mercedes Benz C CLASS W204/S204 8 CYL (Cancellation Kit for Electronic Damping)

Fitted to a 2007-2014 Mercedes Benz C CLASS W204/S204 8 CYL (Cancellation Kit for Electronic Damping), the kit’s biggest effect is on the nose. The M156 V8 puts a lot of weight over the front axle, and the stock adaptive dampers were tuned to disguise that mass on the road rather than control it under repeated hard compression. With the electronic system removed, mechanical damping keeps the front end settled over crests instead of packing down, and rear-end traction improves because the damper is loading the tyre’s contact patch rather than working against a comfort-biased algorithm. Ride height and corner balance can be set to suit the stage rather than the showroom.

About the Tarmac Rally coilover

The Tarmac Rally damper is built around one job: absorbing the impact of broken and uneven surfaces without transmitting that shock straight into the body or unsettling the tyre’s contact patch. Big hits and crest compressions are managed so the impact doesn’t spike through the chassis, and the valving keeps the tyre loaded and gripping through the transition instead of skipping over it. That’s what XYZ frames as stability that lets a driver read the car’s handling accurately from one corner to the next. The base tune carries over settings drawn directly from XYZ’s own tarmac rally programme, rather than a generic road-and-track compromise adapted after the fact.

Fitment for the Mercedes Benz C CLASS W204/S204 8 CYL (Cancellation Kit for Electronic Damping) (2007-2014)

This kit is mapped to chassis code ME07-C, covering the 8-cylinder AMG-engined C-Class saloon and estate built between 2007 and 2014. Because this variant left the factory with electronically controlled adaptive damping, the cancellation kit is required alongside the coilovers to disable that system cleanly rather than leave it fighting the new mechanical dampers.
