XYZ Racing Top Sport Coilovers — Mercedes-Benz G CLASS G63 W463 4WD 2018-2026

The W463 G63’s near two-and-a-half-tonne kerb weight and tall, slab-sided body put more strain on stock damping than almost anything else on sale with an AMG badge, and that mass transfers hard through corners and under trail braking. XYZ Racing’s Top Sport coilover is built for owners who take the G63 beyond motorway cruising, into occasional track days and genuinely quick road driving, without turning the cabin into a punishment cell on the drive home.

Fitted to the G Class G63 W463 4WD, this kit raises damping force and spring rate together so the chassis stops rolling and diving the moment load shifts, while still coping with the broken tarmac and speed humps that come with daily use.

What this coilover does for your 2018-2026 Mercedes Benz G Class G63 W463 4WD

Body control is the headline change. The extra spring rate resists the pitch and roll that a factory-height, factory-rate G63 generates under hard cornering or a stab of front-axle brake, keeping the AMG V8’s weight over the tyres rather than throwing it onto the outside shoulder. The firmer damping curve also does the unglamorous work: it settles the rear axle faster after a compression, so mid-corner bumps do not unsettle the line the way they can on the standard setup. On a vehicle this heavy, controlling wheel traction through a big hit matters as much as outright stiffness, and the added damping keeps the tyre loaded and gripping rather than skipping across the surface. The result on your G63 is a chassis that feels tied down at speed on a circuit or a fast B-road, without abandoning the everyday ride the W463 is still expected to deliver.

About the Top Sport coilover

Top Sport is XYZ Racing’s step up from a street-focused setup, built around 30 to 50 percent more damping force and roughly 2kg/mm more spring rate than the street-tuned kit in the same range. That extra resistance is there to absorb impact from uneven surfaces and larger bumps without the body kicking, and to keep the tyre’s contact patch working rather than skating over disturbances mid-corner. The tune draws directly on XYZ’s own Top Sport race programme, translated into road-legal settings for owners who want that stability without committing to a full race-only ride. It is pitched at track day use and aggressive road driving rather than daily comfort as the priority, which is exactly the brief a 4WD G63 needs if it is going near a circuit.
