XYZ Racing Hollow Rear Brake Kit — Mercedes Benz GLE W166 (2016-2019)

The W166-generation GLE is a heavy machine, well over two tonnes before you add passengers, luggage or a tow ball, and on a nose-heavy SUV the rear axle spends most of its life as the quiet partner. Lean on the brakes hard from motorway speed, drop down a loaded Alpine pass, or hustle a GLE 63 AMG through a sequence of bends, and those rear discs suddenly have real work to do. The XYZ Racing Rear Big Brake Kit for the Mercedes Benz GLE W166 (2016-2019) gives that axle the thermal headroom the factory setup runs short of when it gets warm.

This is a rear-specific kit built around a lightweight two-piece floating disc and an uprated caliper, supplied as a matched pair for the back axle. It is aimed at owners who use the GLE for exactly what it was sold to do: long distances, fully laden, often at pace. Pad compound runs from a Street road material, through a Sport fast-road mix, to a full Racing compound, so the bite you get matches how hard you actually drive the car.

What this brake kit does for your 2016-2019 Mercedes Benz GLE W166

On a vehicle this heavy, the gain you feel first is fade resistance: the two-piece floating disc sheds heat faster and carries less rotational mass, so repeat stops down a hill or after a fast A-road blast stay consistent instead of going long and wooden. The larger rear caliper restores front-and-rear balance, which steadies the GLE under trail-braking and stops the nose diving as sharply into a corner. Choose the Street pad for quiet, low-dust daily commuting, the Sport compound if you mix motorway miles with spirited driving and want a wider heat range, or the Racing material if you load the car up and want maximum confidence under sustained heat. And because the caliper ships in Red, Yellow, Gold, Black, Anodized Black or a custom finish, the upgrade reads as deliberate through the rear wheels rather than an afterthought.

About the rear big brake kit

The disc is a two-piece floating design: a vented ring lightened to cut weight and rotational inertia while opening up more surface for airflow, offered drilled or slotted at the same price. Less mass spinning at the hub means the rear wheels accelerate and slow with marginally less effort, and the extra cooling path keeps the friction surface in its working temperature window for longer. The caliper is a larger-clamp unit matched to the disc, hollow-bodied as standard, with a Hollow Racing upgrade (no dust cover, rated to 1000C, two-year warranty) for hard track work. Three pad compounds, Street, Sport and Racing, mean a single hardware platform covers the daily-driver, fast-road and circuit owner. Painted caliper colours are no-cost, Red, Yellow, Gold, Black or Anodized Black, with a Custom Color in any Pantone for GBP 150 more; premium polished-forged finishes (Titanium, Polished Gold, Polished Silver), candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) and two-tone or titanium centre bells round out the spec. It is a rear-axle kit, designed to be run with or ahead of a matching front upgrade depending on how you use the car.
