XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz CLS C218 4/6 CYL (Cancellation Kit for Electronic Damping) 2011-2018

The Mercedes Benz CLS C218 left the factory with electronic adaptive damping doing the thinking, so any serious coilover swap on this car has to start by taking that control loop out of the equation rather than fighting it. This XYZ Racing Tarmac Rally kit for the CLS C218 4/6 CYL includes the cancellation kit for electronic damping, so the factory air/electronic hardware is disconnected cleanly and the car runs on fixed, mechanically-set damping instead.

At close to five metres of four-door coupe with the engine sitting well forward of the front axle, the C218 loads its nose hard under compression and needs dampers that can actually control that weight transfer rather than just cushion it. Tarmac Rally valving is built around exactly that scenario: sudden hits, camber changes and surface transitions taken at speed on a closed, hard-paved stage rather than a circuit.

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

With the electronic damping cancelled out, the CLS C218 stops second-guessing its own suspension inputs mid-corner. The shim-stack valving in this Tarmac Rally set-up is built to absorb the impact of broken or uneven tarmac without kicking the body around, so a compression that would normally unsettle a car this long instead gets suppressed at the damper before it reaches the chassis. That control keeps more of the CLS’s considerable tyre contact patch working under load, which matters on a nose-heavy 4/6 CYL platform where front-end grip is the limiting factor through fast direction changes. Ride height is coilover-adjustable, so the C218’s low factory stance can be set to match the stage rather than a showroom kerb height.

About the Tarmac Rally coilover

XYZ Racing built the Tarmac Rally line specifically to deal with rough, high-speed closed-road surfaces rather than smooth circuit tarmac. The valving is set up to soak up the shock of a hard, unexpected compression – a broken road edge, a crest, a mid-corner dip – without transmitting that jolt straight into the body, which is what keeps the tyre loaded and the car stable rather than skipping. That stability is the point of the whole design: predictable handling through a sequence of surface changes taken at speed, rather than outright single-hit comfort. The settings come directly from XYZ’s own Tarmac Rally programme, carried over into this kit rather than derived from a generic road spring rate.

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

This kit is built for the Mercedes Benz CLS C218, chassis code ME20-1-C, covering both 4-cylinder and 6-cylinder variants across the 2011-2018 production run. It’s specified with the cancellation kit for electronic damping, so it replaces the car’s factory electronic suspension control rather than working alongside it – confirm your CLS is running the electronically-damped set-up this variant is designed to replace before ordering.
