XYZ Racing Pro Rally Coilovers — Mercedes-Benz AMG GT S/ GT C (Cancellation Kit for Electronic Damping) 2015-2023

The Mercedes Benz AMG GT S and GT C arrived from the factory with AMG RIDE CONTROL, an electronically controlled damper system tuned for road and occasional track use, not for sustained running over gravel, snow or broken stage surfaces. XYZ Racing’s Pro Rally coilover, paired with the cancellation kit for electronic damping, replaces that factory system entirely so the M178 V8’s power can be put down on loose and low-grip surfaces without the ECU fighting a damper set-up it was never calibrated for.

Built for top-flight rally competition rather than road use, this kit gives GT S and GT C owners converting a chassis for gravel or snow stages the mechanical, driver-adjustable damping that rally cars actually run – independent of any factory driving mode, sensor input or software intervention.

What this coilover does for your 2015-2023 Mercedes Benz AMG GT S/ GT C (Cancellation Kit for Electronic Damping)

Cancelling AMG RIDE CONTROL removes the single biggest obstacle to running this chassis off-tarmac: a factory ECU that expects specific damper resistance values and throws faults, or defaults to a limp setting, the moment those values change. With the cancellation kit fitted, the Pro Rally coilover gives you a clean mechanical damping path front and rear, so wheel control over compressions, ruts and jumps is set by spring rate and damper valving rather than a control unit reading road-going sensor data. On the GT C in particular, where the factory fits a wider rear track and active rear-axle steering, having damping decoupled from the electronics keeps that geometry doing its job once the suspension itself is being asked to do something the factory never designed it for. The result is a car that can carry the M178’s torque over loose surfaces without the pitching and rolling a stock adaptive set-up would allow.

About the Pro Rally coilover

XYZ Racing splits its rally-specification suspension into two distinct builds, and it is worth knowing which one you are buying into before committing to a conversion. The first bolts to the original chassis mounting points with no structural changes – a more accessible route for a car that will see mixed use. The second, the professional-grade build this kit belongs to, is intended for cars whose bodywork has already been modified to accept it, which is the approach used in top-flight gravel and snow-stage competition where the suspension has to absorb loads the factory geometry was never designed for. That distinction matters on a chassis like the AMG GT S/GT C, where the standard mounting points and RIDE CONTROL wiring were laid out for a road car, not a stage car. Choosing the professional-type Pro Rally kit means committing to the bodywork changes that let the suspension deliver what it is built for, rather than compromising the geometry to fit an unmodified shell.

Fitment for the Mercedes Benz AMG GT S/ GT C (Cancellation Kit for Electronic Damping) (2015-2023)

This kit is specified for the ME54-C chassis code, covering GT S and GT C variants built between 2015 and 2023. The cancellation kit for electronic damping is a mandatory companion part for these years, since every GT S and GT C left the factory with AMG RIDE CONTROL as standard – confirm the pairing before ordering.
