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

The W222 S-Class was engineered around air springs and adaptive electronic damping, which means converting one to a coilover platform is a deliberate decision, not a casual upgrade. The XYZ Racing Circuit Master coilover for the 4WD W222 (non-MBC hydraulic cars) addresses that head-on: a full mechanical replacement for the factory air system, paired with the cancellation kit needed to silence the electronic damping ECU so the dash stays clean and the car drives without fault codes.

This is the spec for owners running the W222 harder than Stuttgart ever intended – track use, hill climbs, or a settled, lower stance that the factory air struts simply cannot hold over a season of real driving.

What this coilover does for your 2014-2020 Mercedes Benz S CLASS W222

A two-tonne luxury saloon on aged air springs leans, wallows, and eventually leaks. Switching to the Circuit Master gives the W222 a body that actually answers steering inputs instead of taking a beat to settle on its outside corner. Damping is adjustable so you can run the car compliantly enough for B-road cruising and then firm it up for circuit work without changing hardware. Ride height comes down predictably and stays there – no more compressor cycling, no more morning-after sag. The 4WD-specific valving keeps front and rear in phase under power, which matters on a car this heavy when the all-wheel-drive system is pulling hard out of a corner.

About the Circuit Master coilover

The Circuit Master sits at the track-focused end of the XYZ Racing range. Construction is monotube with a large-diameter piston, giving you the oil volume and heat capacity needed to control a 2,000+ kg chassis through repeated heavy braking zones. Damping is independently adjustable so compression and rebound can be tuned to the spring rate and the surface. Spring rates are selected for circuit duty on a heavy luxury platform – stiff enough to manage weight transfer, supple enough to keep the contact patch loaded over kerbs. Ride-height adjustment is separated from preload, which is the correct way to corner-balance a car and is essential on the W222 given its weight distribution. The included cancellation kit handles the electronic damping signal so the conversion is properly resolved at the ECU level, not bodged around it.

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

Chassis code ME65-C, covering 2014 through 2020 W222 cars with the 4WD drivetrain and the non-MBC hydraulic suspension layout. The kit ships with the cancellation module required for cars fitted with electronic damping from the factory, so the dash and fault-code behaviour stay resolved after installation.
