XYZ Racing Circuit Master Coilovers — Mercedes-Benz S CLASS W222 (NON MBC hydraulic or 4WD) (Cancellation Kit for Electronic Damping) 2014-2020

The W222 S-Class is a two-tonne luxury barge that was never meant to be wrung out on a circuit, which is precisely why the Circuit Master kit for this chassis is such a specific piece of engineering. With the factory Airmatic or Magic Body Control deleted, the car suddenly behaves like a proper steel-sprung saloon – and that exposes both the weight and the geometry. This kit is built to give the W222 a flat, controlled stance and the damping authority to actually corner, without leaving the cabin feeling like a kit car.

XYZ’s Circuit Master sits at the track-focused end of the catalogue, and on a 2014-2020 S-Class it is aimed squarely at owners running events, hillclimbs, or fast private-circuit days in a car the factory engineered for autobahn cruising. The included electronic damping cancellation kit is the part that makes this remotely viable – without it, the ECU throws a fault the moment the air struts come off.

What this coilover does for your 2014-2020 Mercedes Benz S Class W222 (NON MBC Hydraulic Or 4WD) (cancellation Kit For Electronic Damping)

The first thing you feel on a W222 with Circuit Master fitted is the absence of pitch. Heavy braking from speed no longer dives the nose into the bumpstops, and turn-in becomes immediate rather than the slow, hydraulic roll the factory air setup defaults to. The 36 clicks of damping adjustment give you a genuine working window – soft enough to live with on broken UK B-roads, firm enough to keep two tonnes of luxury saloon flat through a long fast corner. Ride height is fully independent of spring preload, so you can drop the W222 to a sensible visual height without pre-loading the springs and ruining the damper stroke. The cancellation kit handles the Airmatic ECU side of the conversion, so the dashboard stays clean and the car stops trying to self-level against hardware that no longer exists.

About the Circuit Master coilover

Circuit Master is XYZ Racing’s circuit-biased kit, sitting above the road-focused Super Sport tier and pitched at owners who want a serious track tool without going to the fully bespoke Racing Spec. Construction is monotube with a 30-stage Japanese-sourced oil package, pillow-ball top mounts where the chassis permits, and a hardened steel body finished to resist UK salt and brake dust. Single-adjuster 36-click damping controls both compression and rebound in a fixed ratio, which keeps the setup simple to tune trackside without juggling two knobs. Spring rates on the W222 application are set higher than the Super Sport equivalent to deal with the kerb weight, and the kit ships with the electronic damping cancellation module pre-configured for the non-MBC, non-4WD W222 variants. Ride height is set via the lower bracket rather than spring preload, which is the correct way to do it and preserves full damper travel.

Fitment for the Mercedes Benz S CLASS W222 (NON MBC Hydraulic Or 4WD) (Cancellation Kit For Electronic Damping) (2014-2020)

This kit fits the 2014-2020 W222 S-Class on the chassis code ME63-C, specifically the variants that left the factory WITHOUT MBC hydraulic suspension and WITHOUT 4MATIC all-wheel drive. The included cancellation kit handles the electronic damping ECU on cars originally fitted with adaptive struts. If your W222 has Magic Body Control or 4MATIC, this is not the correct kit – check the alternate W222 listings.
