XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz G CLASS G63 W463 4WD (Cancellation Kit for Electronic Damping) 2018-2026

The W463 G63 is a 2.5-tonne ladder-frame anomaly with a hand-built AMG V8 over the front axle and a body shape unchanged in spirit since 1979. Stock it rides on adaptive dampers that AMG tunes for Autobahn cruising and gentle green-laning, not for the way most UK owners actually use the car – tarmac stages, fast B-roads, and the occasional event where the standard ride height and soft body control simply won’t keep up.

The XYZ Racing Tarmac Rally coilover for the 2018-2026 G63 W463 is built for that gap, and it ships with the cancellation kit needed to bypass the factory ADS module cleanly. This is a rally-spec damper applied to a chassis most people never think to upgrade properly – and the difference, once the body roll and float disappear, is the kind of thing that recalibrates how you drive the car.

What this coilover does for your 2018-2026 Mercedes Benz G Class G63 W463 4WD (Cancellation Kit for Electronic Damping)

The first thing you feel is the W463 stops behaving like a tall, soft truck and starts behaving like a vehicle with a defined damper curve. Body roll into a third-gear corner halves. The nose stops diving on the brakes, which on a G63 with that engine mass is the single biggest handling complaint owners have. Turn-in becomes a deliberate input rather than a request the chassis considers and acts on a moment later. Ride height is fully adjustable, so you can drop the stance to close the wheel-arch gap that the standard car wears at speed, or lift for green-lane clearance when the route demands it. The cancellation kit means no dashboard fault, no limp mode, no ADS warning – the factory electronics see the new dampers as compliant and stay quiet.

About the Tarmac Rally coilover

Tarmac Rally sits in XYZ’s competition tier, developed for sealed-surface stage use where surface quality varies but grip is generally high. The damper bodies are monotube, separated-piston construction, which keeps oil and gas apart under sustained heavy work and prevents the fade you’d get from a twin-tube unit on a long stage. Damping is independently adjustable on bump and rebound, giving you genuine tuning range rather than a single knob that compromises one to set the other. Spring rates are matched to the G63’s mass and weight distribution rather than carried over from a lighter platform. The cancellation harness handles the W463’s ADS electronics so the install is clean – no aftermarket warning lights, no ECU sulk.

Built specifically for the W463 G63 4WD platform (chassis ME61-C) across the 2018-2026 production run. The kit includes the electronic damping cancellation hardware required for this chassis – without it, removing the factory ADS dampers throws a fault. Confirm trim and any factory off-road or AMG dynamic options against your VIN before ordering.
