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

The AMG GT R left Affalterbach with adaptive electronic dampers wired into the car’s ECU – brilliant for a road-legal Nürburgring lap record, but a fixed liability the moment you want a damper curve tuned purely for one circuit and one set of tyres. XYZ Racing’s Racing Spec coilover for the GT R ships with the cancellation kit that takes the factory electronic damping signal out of the equation, so the car runs on mechanical, driver-set compression and rebound instead of a computer’s compromise.

That matters most in time-attack and full track sessions, where the GT R’s wide rear track and biturbo V8 punch a lot of load through the rear axle under braking and on corner exit. Racing Spec is built for exactly that scenario: a fixed, race-derived platform rather than a daily-comfort setup, aimed at drivers who already know they are not sharing this car with a commute.

What this coilover does for your 2017-2023 Mercedes Benz AMG GTR

Once the electronic damping cancellation kit is fitted, the GT R’s suspension response comes entirely from the coilover’s own valving rather than a control module reacting a beat behind the road. On a car this heavy at the rear, that means corner-entry rotation you can feel and repeat from one session to the next, instead of a damper map that softens itself the moment the ECU decides you are pushing. Ride height and corner-weighting become adjustable to a fixed track setup, which helps correct the nose-heavy transition understeer the GT R shows when its adaptive dampers default to a comfort-biased map. Under trail-braking into slower corners, the fixed valving keeps the front axle loaded predictably – exactly where the factory system’s electronic lag costs the most time. The result is a Mercedes Benz AMG GTR that behaves the same on lap one and lap twenty, not a suspension that recalibrates itself mid-session.

About the Racing Spec coilover

XYZ Racing’s Racing Spec damper is the brand’s dedicated track and race product, built off setup data logged from XYZ’s own participation in circuit racing, including WTCC entries. Where the road-focused ranges chase comfort compromises, Racing Spec is calibrated around corner speed and lap time, using construction and valving pulled from cars actually run on a grid. For heavily modified cars – wide-body kits, aero changes, uprated brakes, forced-induction work – XYZ also offers a bespoke version of this damper: send over what has been changed on the car and which circuit it is aimed at, and the valving gets built around that specific combination rather than a generic track spec. On the GT R that bespoke route is particularly relevant, since a car already carrying factory-level aero and a biturbo V8 sits close to the aggressively-upgraded end of what this custom service is built to handle. The standard Racing Spec kit remains the base every custom build starts from, so buyers not chasing a fully bespoke setup still get the same racing-derived platform.

Fitment for the Mercedes Benz AMG GTR (2017-2023)

This kit fits the Mercedes Benz AMG GT R, chassis code ME39-C, across the 2017 to 2023 production run, and includes the cancellation kit required to run this coilover in place of the factory electronic damping system. Confirm your car is the GT R variant covered by chassis code ME39-C before ordering, since the wider AMG GT range uses different suspension hardware.
