XYZ Racing Super Sport Coilovers — Mercedes-Benz CLS C218 8 CYL (Cancellation Kit for Electronic Damping) 2011-2018

The V8 C218 CLS left the factory riding on Airmatic air springs and electronically controlled dampers – a setup tuned for wafting down a motorway, not for loading the nose into a fast corner or holding a fixed ride height through a full track session. Swap that system out and the car’s ECU still expects to see the electronic damper signal, which is why this kit isn’t just a coilover – it’s a Super Sport kit paired with a cancellation module for the factory electronic damping.

For a four-door coupe carrying a V8 up front, that combination matters. The Super Sport spec gives the CLS C218 a fixed, adjustable platform for fast-road driving and the occasional weekend track outing, without the Airmatic’s variable-rate compromises or the warning lights that show up when you remove it without properly nulling the signal.

What this coilover does for your 2011-2018 Mercedes Benz CLS C218 8 CYL

Removing the Airmatic air struts and electronic dampers takes a heavy amount of unsprung mass and control-system latency out of the front end, which shows up immediately in turn-in response on a car that’s always had to manage a big V8’s weight over the front axle. The 36-way damping adjustment lets you set the CLS firmer for a track session and back off for the drive home, rather than being stuck with whatever compromise Mercedes’ adaptive system chose for you. Independent ride height adjustment means you can drop the car for a lower centre of gravity and tighter wheel-arch gaps without touching spring rate, and because the kit includes the cancellation piece for the electronic damping circuit, the dash stays clear of suspension fault warnings that a straight coilover swap on this chassis would otherwise trigger.

About the Super Sport coilover

XYZ Racing’s Super Sport line is built around eliminating the harshness that a firmer, fixed-rate spring setup usually brings on rough UK B-roads and motorway expansion joints, while still giving the driver real control over how the car sits and moves. The 36-way damping adjustment covers a wide enough range to run soft for a daily commute or firm up meaningfully for track work, and the threaded body allows ride height to be set independently of preload. On the CLS C218, that adjustability is paired with the electronic-damping cancellation kit so the factory suspension control module is properly accounted for rather than left throwing errors. The result is a damper platform built to work equally on the commute and on a trackday, rather than one tuned exclusively for one or the other.

Fitment for the Mercedes Benz CLS C218 8 CYL (2011-2018)

This kit is specified for the C218-generation Mercedes-Benz CLS with the V8 engine, chassis code ME20-2-C, covering the 2011 to 2018 model years. It’s built specifically for cars fitted from the factory with Airmatic and electronic damping control, which is why the cancellation kit for the electronic damping system is bundled in rather than sold separately. Confirm your car carries the factory electronic suspension before ordering, since this variant is matched to that setup.
