XYZ Racing Racing Spec Coilovers — Mercedes-Benz AMG GT 4-DOOR COUPE (X290) 4WD 8CYL (Cancellation Kit for Electronic Damping) 2018-2026

The X290 4-door Coupe carries its twin-turbo V8 well behind the front axle line, but at over 1.9 tonnes with four driven wheels it still needs a chassis that can shed the factory’s adaptive damping electronics before it starts behaving like the two-door GT it’s related to. XYZ Racing’s Racing Spec coilover is built for exactly that swap: a fully mechanical, fully adjustable damper in place of the standard AMG Ride Control system, paired with a cancellation kit so the dash stays free of fault codes once the electronic dampers are out of the loop.

This is the track-day and time-attack spec in the XYZ Racing range, not the fast-road option. It’s aimed at AMG GT 4-Door owners who already know their car’s electronic damping ceiling and want a set-up they can actually adjust corner by corner instead of leaving to a control module.

What this coilover does for your 2018-2026 Mercedes Benz AMG GT 4-Door Coupe

With the factory electronic dampers cancelled out, ride height and damping force stop being a compromise negotiated by software and become settings you control directly. On a 4WD car of this weight, that matters most under trail-braking into slower corners, where the AMG GT 4-Door’s mass wants to keep loading the front outside tyre well past the point the standard set-up gives useful feedback. Lowering the centre of gravity and firming the front end reduces that push, sharpening turn-in without leaning on the drivetrain to bail you out mid-corner. At the rear, mechanical damping keeps the car settled under power out of a hairpin instead of letting the all-wheel-drive system mask a chassis that’s still moving around underneath it. The result is a car that changes direction on your inputs, not on a comfort-biased algorithm.

About the Racing Spec coilover

XYZ Racing developed the Racing Spec damper specifically for circuit racing, with the base tune drawn directly from the brand’s involvement in WTCC competition rather than road-car comfort testing. For cars carrying more aggressive modifications – factory-level aero, brakes, or power upgrades – XYZ Racing also offers a custom-valved version of this same damper: send over the spec of what’s been changed on the car and the circuit it’ll be run on, and they’ll build shock absorbers tuned to that specific set-up rather than a generic track preset. On the AMG GT 4-Door this means the cancellation kit isn’t a bolt-on afterthought – it’s engineered so the mechanical damper fully replaces the electronic system’s job, with no half-measure blend between the two.

Fitment for the Mercedes Benz AMG GT 4-Door Coupe (2018-2026)

This kit is built for the X290-chassis AMG GT 4-Door Coupe, 4WD, V8 models, across the 2018-2026 build range, specifically the version fitted from factory with electronic damping – hence the cancellation kit bundled with the coilovers. Confirm your car matches this chassis code and drivetrain configuration before ordering, since the electronic-damping cancellation hardware is specific to this set-up.
