Caliper render for this kit:

The W463 G350d carries approximately 2,500 kilograms into every braking zone, a mass figure that exposes the limits of the factory front-axle hardware sooner than most road cars will ever reveal. That weight, combined with the OM642 diesel’s substantial torque arriving from idle upward, generates thermal loads that accumulate across repeated hard stops in ways the standard components were not designed to manage with any headroom to spare.
This front big brake kit from XYZ Racing addresses that arithmetic directly. Built specifically for the W463 generation and supplied as a pair of front discs and calipers, it upgrades the hardware at the axle that handles the majority of deceleration duty on the G-Class’s body-on-frame platform, where the front end takes the brunt under any serious braking event.
What this brake kit does for your 2014-2018 Mercedes Benz G350D W463
The G350d’s solid front axle, an arrangement that has all but vanished from road-going vehicles outside the G-Class lineage, concentrates braking load into a relatively compact geometry, and at 2,500 kilograms that load builds heat quickly under sustained hard driving. The two-piece floating discs use a hollow-vane design that dissipates that heat more effectively than the standard item, recovering consistent pedal firmness between stops rather than letting fade compound with each successive deceleration, and the floating ring expands without warping. Three pad compounds, Street, Sport, and Racing, span the G350d’s actual range of use, from quiet, low-dust mixed motorway and off-road duties through to committed performance sessions. Discs are offered drilled or slotted at the same price. Caliper hardware is available in Red, Yellow, Gold, Black, and Anodized Black at no extra cost, with a custom Pantone match and premium polished-forged or candy finishes, making the upgrade visible through the W463’s substantial alloy openings.
About the front brake kit
The two-piece floating disc is the defining engineering feature of this kit: the hollow-vane casting reduces rotating mass while maintaining sufficient thermal capacity to absorb the energy generated by decelerating a vehicle in the G350d’s weight class. Heat is shed more readily than through solid-cast alternatives, keeping friction materials within an operating range where bite remains predictable through successive stops rather than softening as temperatures climb. The caliper is a hollow-body forging as standard, with an optional Hollow Racing caliper, no dust cover, rated to 1000C, two-year warranty, for harder use. Pad selection runs across Street, Sport, and Racing, giving meaningful scope from everyday mixed-use driving to track-day or performance road applications. 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 specifically, where the heaviest braking loads on the W463 platform are concentrated.
Fitment for the Mercedes Benz G350D W463 (2014-2018)
This kit covers the W463-generation G350d across the 2014 to 2018 model years, the final production run of that body before the W464 replacement. The W463 uses a solid front axle suspension arrangement, and the kit is engineered to that specific geometry, not a universal fitment adapted to suit. Confirm your W463’s model year before specifying.

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.
