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

The X290’s four-wheel-drive V8 hides serious mass over the front axle, and the factory electronic damping was tuned around that weight with comfort as much as control in mind. Cancelling that system and fitting XYZ Racing Top Sport coilovers hands the damping decision back to you, with a mechanical setup calibrated for a car that already has the traction to put big power down.

Top Sport sits between XYZ’s fast-road and full competition ranges, built for owners who want a car that’s genuinely usable on the road but sharp enough to take to a track day without feeling out of its depth. On a car as heavy as the AMG GT 4-Door, that middle ground matters: too soft and the nose wallows under braking, too stiff and the ride becomes punishing on UK B-roads.

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

Fitting this kit raises spring rates by roughly 2kg/mm over the standard electronic setup, or an equivalent 30-50% increase in damping force, which tightens body control through direction changes without simply making the car harder. On a 4WD car putting power through all four corners, that reduction in body roll translates directly into better traction under acceleration out of a bend, since the tyres are working from a more stable platform rather than fighting suspension movement. The increased damping also does the job the factory system did electronically, only now it’s fixed and predictable rather than reactive – useful when you’re loading the car hard on track and don’t want the character of the suspension changing mid-corner. Ride height becomes fully adjustable too, so you can drop the AMG GT 4-Door’s stance and lower its centre of gravity without touching spring rate. For a car this size and this heavy, cutting body movement is the difference between feeling the chassis and just feeling the mass shift around.

About the Top Sport coilover

Top Sport coilovers are built around XYZ Racing’s track-day experience, with damping and spring rate settings derived directly from what the brand has learned running cars in anger rather than from a desk-based spec sheet. The core job is absorbing the hit from poor surfaces and larger bumps without letting that impact unsettle the chassis or break traction – XYZ describes it as suppressing shock to the body so the tyre keeps its grip rather than skipping over the imperfection. That composure is what buyers actually want from a fast-road-and-occasional-track kit: a car that stays flat and predictable when you lean on it, not one that’s simply firmer for the sake of it. The kit is built for aggressive road driving as much as for circuit use, which is the right brief for a 4WD, 8-cylinder grand tourer that’s more likely to see a Sunday blast and the odd trackday than a full race season.

Fitment for the Mercedes Benz AMG GT 4-Door Coupe (X290, 2018-2026)

This kit is specified for the X290-chassis AMG GT 4-Door Coupe across the full 2018-2026 production run, covering the 4WD 8-cylinder variants fitted from the factory with electronic damping. Because this application replaces the electronic system entirely, it includes the cancellation kit needed to run mechanical coilovers on a car that expects an active damper signal – fit it alongside the coilovers rather than as an optional extra.
