Caliper render for this kit:
The 2019-onwards W463 was the first G-Class to abandon its solid front axle for double-wishbone independent suspension, a change that finally let the twin-turbo V8’s performance translate into something resembling dynamic precision. What it did not change was the mass: the G63 remains one of the heavier vehicles in the AMG range, and under hard braking that weight transfers aggressively forward onto the front axle. The factory stoppers are calibrated for composed road use, but repeated heavy applications, a mountain pass descent, a spirited fast-road run, a track session, will ask questions they were not necessarily designed to answer repeatedly.
The XYZ Racing front brake kit for the 2019-2026 W463 G63 AMG approaches the problem from the disc outward. It fits as a pair of front discs and calipers, the two-piece floating disc construction improves airflow through the internal vane structure, and three pad compounds allow the installation to be matched to how the vehicle is actually used.
What this brake kit does for your 2019-2026 Mercedes Benz G63 AMG 4.0 V8 W463
A two-piece floating disc rejects heat more aggressively than a conventional vented disc by increasing airflow through the internal vane structure as the wheel turns, and under the thermal loads created by decelerating the G63’s substantial mass from speed that advantage becomes tangible. The floating ring expands without warping, and reduced rotating mass aids response. Street is the quiet, low-dust choice for year-round road and cold-start city driving; Sport lifts the thermal ceiling for more committed fast-road work; Racing handles the sustained heat loads of a circuit environment, where the G63’s weight creates long, repeated braking zones. Discs are offered drilled or slotted at the same price. Caliper colour, Red, Yellow, Gold, Black, or Anodized Black at no extra cost, with a custom Pantone match and premium polished-forged or candy finishes, gives the installation a visual presence that reads as intentional against the W463’s imposing proportions.
About the front brake kit
The two-piece floating discs differ from standard vented discs in the geometry and volume of the internal vane structure: the greater internal airflow capacity means the disc draws heat from the friction surface more effectively under load, maintaining consistent bite where a conventional disc would begin to fade. XYZ Racing’s front kit pairs these discs with multi-piston calipers, a hollow-body forging as standard, with an optional Hollow Racing caliper, no dust cover, rated to 1000C, two-year warranty, for serious track use. Three pad grades, Street, Sport, and Racing, cover daily commuting through fast-road driving to circuit work without requiring a separate pad set for each application. Braided lines firm the pedal, and centre bell upgrades in five anodized colours or titanium are selectable at checkout. The kit addresses the front axle as a complete unit, providing a matched disc-and-caliper specification rather than combining upgraded discs against stock hardware.
Fitment for the Mercedes Benz G63 AMG 4.0 V8 W463 (2019-2026)
This front brake kit is specified for the Mercedes Benz G63 AMG 4.0 V8 in W463 chassis form, covering the 2019 to 2026 model year range. The kit addresses the front axle only; rear brake specifications are unchanged by this installation. Verify your chassis identification plate confirms W463 before ordering.

Choosing your spec
Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.
Brake pads — Street, Sport or Racing
Every kit ships with a full set of high-performance pads; the compound is your call.
Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.
Caliper grade — Hollow vs Hollow Racing
Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.
Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 286–380mm (front). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.
Caliper colour & finish
Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).
Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.
Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).
Centre bells
The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
