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

The CLS C218’s V8 models left the factory riding on AIRMATIC air springs and electronically controlled dampers, a system built for motorway comfort rather than a stage’s compressions and crests. Fitting a coilover kit to this chassis means dealing with that factory wiring first, and this cancellation kit does exactly that: it lets the Tarmac Rally kit’s own valving take over without the dash lighting up with suspension fault codes.

Tarmac Rally is XYZ’s damper for sealed-stage work on unbroken tarmac roads, not track circuits with clean, repeatable surfaces. It’s built to soak up the mid-corner ridges, camber changes and surface breaks that a closed-road stage throws at a heavy, rear-biased four-door coupe, without losing the body control a stage average demands.

What this coilover does for your 2011-2018 Mercedes Benz CLS C218 8 CYL (Cancellation Kit for Electronic Damping)

With a V8 under the bonnet and the CLS’s characteristic nose-heavy stance, this chassis carries real mass through direction changes, and stock air suspension was tuned to hide that mass rather than manage it directly. Swapping to a coilover with damping set from XYZ’s own tarmac rally experience gives the car a platform that stays flatter under load and settles faster after a compression, instead of wallowing on soft air springs. The valving is calibrated to absorb the hit from broken tarmac and mid-corner ridges without kicking the body upright, which keeps all four tyres loaded and working rather than skipping over the surface. That translates into more usable traction out of a bumpy apex and a car that holds its line through a rough section instead of stepping wide. On a long, heavy coupe like the C218, that stability is the difference between a stage car that’s driveable flat-out and one that’s fighting you back.

About the Tarmac Rally coilover

XYZ’s Tarmac Rally coilover is built specifically around sealed-stage tarmac work rather than closed-circuit lapping. The damper’s valving is set up to soak up sharp-edged impacts and larger compressions without transmitting the full hit into the chassis, which matters when a stage surface can go from smooth to broken with no warning. That absorption is aimed squarely at keeping the tyre in contact with the road through the hit, since a wheel that’s been thrown off the surface is a wheel that isn’t generating grip. The same valving also reins in body movement after the impact, so the car settles back onto its line rather than continuing to pitch and roll through the next few metres. XYZ has carried that setup over directly from its own tarmac rally programme, so the settings on this kit reflect damper behaviour proven over repeated stage running rather than a generic road-and-track compromise. For this CLS C218 application, that base tune is paired with the cancellation kit needed to run the coilovers cleanly once the factory electronic damping is out of the equation.

Fitment for the Mercedes Benz CLS C218 8 CYL (Cancellation Kit for Electronic Damping) (2011-2018)

This kit is fitted to the Mercedes Benz CLS C218 in 8-cylinder form, covering the 2011 to 2018 model years under chassis code ME20-2-C. It’s specified as a cancellation kit for electronic damping, so it replaces the factory AIRMATIC/ADS electronics rather than running alongside them. Confirm your CLS is a V8-engined C218 within this year range before ordering, since the cancellation hardware is matched to that electronic damping setup.
