XYZ Racing Circuit Master Coilovers — Mercedes-Benz S CLASS W222 4WD (NON MBC hydraulic) 2014-2020

The W222 S-Class is a two-tonne luxury barge with air springs from the factory, and the moment you remove that air system you are committing to a properly engineered steel coilover that can carry the weight without turning the car into a skateboard. The XYZ Racing Circuit Master coilover is built for owners who have either lost a Magic Body Control hydraulic strut to age and want a permanent fix, or who want the W222 to actually settle into corners rather than wallow through them.

Circuit Master sits at the firmer end of the XYZ range, so this is a kit for the S-Class owner who treats their car as a fast tourer rather than a back-seat limousine. It replaces the entire compliant air setup with a damper-and-spring platform you can set once and forget, with the ride height dropped to whatever stance suits the car.

What this coilover does for your 2014-2020 Mercedes Benz S Class W222 4WD (NON MBC Hydraulic)

Removing the OEM air suspension and dropping a steel coilover under a 4MATIC W222 immediately changes how the car carries its mass. Body roll through long sweepers tightens up, the front end stops floating mid-corner under throttle, and turn-in becomes something you can actually meter rather than wait for. The 30-way damping adjustment is the headline spec here, and on a car this heavy it matters – you want enough compression damping to control the sprung mass without battering occupants over expansion joints. The pillowball top mounts give you direct steering feedback that the rubber-mounted OEM setup deliberately filters out, which is the entire point of the upgrade for a driver-focused owner. Ride height is independently adjustable from spring preload, so you can drop the car without pre-loading the springs into a harsh setting.

About the Circuit Master coilover

The Circuit Master is a 30-level damping-adjustable monotube coilover with separate ride-height and spring-preload adjustment, which on a heavy long-wheelbase saloon is the only sane way to set the car up. The monotube layout puts the gas charge above the oil and keeps damper fade in check on longer drives – relevant when the car is carrying four adults plus luggage at motorway speeds. Spring rates are specified to suit the W222’s mass distribution, with the front carrying the bulk of the engine load and the rear set up to keep the 4MATIC driveline planted. Pillowball top mounts replace the OEM rubber bushings for sharper response, and the hardware is finished to handle UK winter salt without seizing the adjuster threads. This is a long-service kit rather than a stripped-out track item – the engineering brief is "make a luxury car handle properly" rather than "make a race car comfortable enough to drive home".

Fitment for the Mercedes Benz S CLASS W222 4WD (2014-2020)

This kit fits the W222-generation S-Class with 4MATIC all-wheel drive, chassis code ME65, model years 2014 to 2020. Critically it is specified for cars WITHOUT the MBC hydraulic system – if your S-Class has Magic Body Control with the forward-facing road-scanning camera and hydraulic struts, this is the wrong reference and you need the MBC-specific kit. Standard AIRMATIC cars are the correct fitment here.
