XYZ Racing Hollow Rear Brake Kit — Mercedes Benz G350D W463 (2014-2018)

A two-and-a-half-tonne body-on-frame 4×4 riding on a live rear axle asks a great deal of its rear brakes, and the G350d W463 is no exception. Long descents, a loaded boot and the diesel’s low-down torque all push heat into the rear corners that the factory setup struggles to shed. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz G350d W463 swaps that rear stopping hardware for a larger, better-ventilated two-piece disc and a fixed caliper sized for the G-Wagen’s mass.

This is rear-axle hardware for owners who actually work the chassis, towing, green-laning, motorway miles two-up with luggage, rather than chasing a single number. The hollow-vane disc construction trims unsprung weight at a corner where the solid rear axle already carries plenty, and gives the pads a cleaner, more consistent bite once the brakes are hot.

What this brake kit does for your 2014-2018 Mercedes Benz G350d W463

On the road you notice it first as a firmer, more progressive pedal. The fixed caliper flexes less than the sliding factory unit, so the bite point stays where you left it whether the brakes are cold on the school run or baked after a long Alpine descent. Pad compound is the lever here: Street suits everyday G-Wagen duty, Sport adds bite and heat range for loaded or spirited driving and the odd track outing, and Racing is there if the truck sees competition use. The larger rear disc adds thermal mass, which is what stops a heavy 4×4 cooking its rear brakes on repeated hard stops.

About the Hollow Rear Brake Kit

XYZ Racing’s hollow-vane disc removes material from the two-piece floating rotor without touching the friction surface, cutting rotating and unsprung mass while leaving more internal area to move heat. The kit is a rear-axle fixed-caliper conversion supplied as a matched pair: a one-piece caliper clamping an uprated disc, supplied with your choice of pad compound from Street, Sport or Racing. The caliper is hollow-bodied as standard, with an optional Hollow Racing upgrade for serious off-road or competition use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Calipers come in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone shade and premium polished-forged or candy finishes available, so the view through the wheel can be as discreet or as loud as you want. Everything is dimensioned around the rear of the W463 platform rather than adapted from another fitment, which counts on a vehicle whose weight and axle layout are unlike anything else in the range. The brief throughout is repeatable heat management and a steady pedal.
