XYZ Racing Circuit Master Coilovers — Mercedes-Benz AMG GTR (Cancellation Kit for Electronic Damping) 2017-2023

The AMG GT R’s factory adaptive damping is tuned for a car that splits its time between road and circuit, which means it never fully commits to either. The XYZ Racing Circuit Master coilover replaces that compromise with a fixed, mechanically adjustable damper built for sustained lap-time work, and this cancellation kit variant removes the electronic control side of the equation entirely so the new dampers run on their own settings instead of fighting the GT R’s factory ECU.

Circuit Master sits at the top of XYZ Racing’s coilover range: a track-focused platform for drivers who want repeatable behaviour session after session rather than a damper that recalibrates itself lap to lap. On a rear-engined, twin-turbo V8 car with the AMG GT R’s weight balance, that consistency is what lets you trust the same braking point and the same rotation on lap ten as lap one.

What this coilover does for your 2017-2023 Mercedes Benz AMG GTR (Cancellation Kit for Electronic Damping)

With the electronic damping cancelled out, every adjustment made on the Circuit Master’s three knobs is the one that actually reaches the wheel, with no ECU override smoothing it back out mid-corner. The 9,720-way adjustment range gives enough resolution to separate compression and rebound settings on a car that already generates serious mechanical grip through its wide rear track, rather than leaving you with a handful of preset modes. Ride height is fully adjustable through the coilover body too, so you can correct the stance change that comes with stiffer spring rates and keep the GT R’s aero balance close to where Mercedes-AMG set it from the factory. The net effect on track is a car that loads its outside tyre predictably through fast direction changes instead of hunting for the right damping curve mid-corner.

About the Circuit Master coilover

Circuit Master is built around damper hardware developed and tested with XYZ Racing’s own teams across international circuits. Three external knobs control the valving, and between them the range works out to 9,720 individual adjustment combinations, enough to fine-tune compression and rebound independently rather than moving one dial and hoping the rest follows. That resolution comes from a small-orifice oil-passage design inside the damper body, and the trade-off is that oil moving through those narrow passages can produce a faint clicking or ticking noise over sharp bumps on track. That’s expected behaviour for this design, not a fault. This is a damper built for repeated circuit sessions rather than daily ride comfort, and the cancellation kit fitment for the AMG GT R lets that circuit-tuned hardware run without the factory electronic damping system trying to intervene.

Fitment for the Mercedes Benz AMG GTR (cancellation Kit For Electronic Damping) (2017-2023)

This kit is specified for the Mercedes Benz AMG GT R built between 2017 and 2023, chassis code ME39-C, and is the cancellation-kit variant designed for cars fitted with the factory electronic damping system from new. Confirm your GT R falls within this build range before ordering, since the cancellation hardware is specific to this electronically-damped chassis configuration.
