XYZ Racing Top Sport Coilovers — Mercedes-Benz AMG GTR 2017-2023

The Mercedes-AMG GT R is a rear-driven, twin-turbocharged V8 built around a factory adaptive damping system tuned to Affalterbach’s own ride height and spring settings. XYZ Racing’s Top Sport coilover kit for the AMG GTR (2017-2023) replaces that adaptive setup with a kit built for owners who split their time between occasional track days and daily driving, rather than a car parked permanently on slicks.

This is a full ride-height and damping kit, not a spacer or a spring-only swap. It’s built for GT R owners chasing sharper turn-in and better-controlled weight transfer under hard braking and quick direction changes, while keeping the ride manageable on the road the rest of the week.

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

Fitted to the GT R, the Top Sport kit steps damping up by roughly 30-50% over XYZ’s street-spec setting, or adds around 2kg/mm to the spring rate, depending on how you configure it. That extra control matters on a car sending all of its power through the rear axle alone: it suppresses the body movement that shows up as squat under hard acceleration out of a corner and dive under braking into one. Firmer damping also keeps the contact patch working across broken pavement and mid-corner bumps instead of letting the tyre skip, which on a rear-driven car this powerful is where the traction actually lives. Ride height adjustment lets you correct the GT R’s stance without disturbing the geometry the factory dampers were originally tuned around.

About the Top Sport coilover

XYZ’s Top Sport line increases damping force by around 30-50% over the street-oriented setting, or trades that for roughly a 2kg/mm increase in spring rate, depending on which way you want the car to feel. The idea is to absorb the impact of rough tarmac and big compressions without transmitting it straight into the chassis, while keeping the body under control so the tyres keep their contact patch through a bump rather than skipping across it. The settings come out of XYZ’s own Top Sport racing programme, translated for road-legal use. It sits in the middle of XYZ’s coilover range: firmer and more controlled than a street kit, but still set up to be driven to the circuit and home again rather than trailered, which is exactly the brief for a GT R owner doing occasional track days.

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

This kit is a direct fit for the Mercedes Benz AMG GTR, chassis code GTR, across the full 2017-2023 production run, replacing the factory adaptive damper units at each corner without cutting or modifying the strut towers or mounting points.
