XYZ Racing Hollow Front Brake Kit — Bmw X5 F15 (2013-2018)

The F15 X5’s kerb weight sits between 2,165kg at the lighter end of the range and nudges 2,360kg in xDrive50i specification, a figure that makes the front axle’s braking workload a meaningful engineering question rather than an afterthought. That mass, combined with the xDrive system’s front-weighted bias under hard braking, puts enormous thermal demand on the front discs during any sustained stop sequence. XYZ Racing’s Hollow front brake kit gives the F15’s nose the capacity to deal with it properly.

It is a single-axle kit, a matched pair of front calipers and two-piece floating front discs for the left and right corners. Three pad compounds, Street, Sport and Racing, cover the realistic spread of how an X5 actually gets used. Street handles the day-to-day with enough in reserve for the odd spirited motorway run. Racing exists for the owners who have discovered, at a BMW club track day or an alpine descent with a fully laden car, that the factory setup runs out of confidence before they do.

What this brake kit does for your 2013-2018 Bmw X5 F15

Stopping 2.2 tonnes from speed loads the front axle disproportionately, brake balance pushes the load further forward the harder you stop, and the F15’s xDrive architecture does nothing to redistribute that physics. The Hollow front kit addresses heat accumulation directly: the hollow-vane disc routes air through the rotor body to manage the thermal cycles that build through repeated hard stops, and the two-piece floating construction lets it expand without distorting, which translates to more consistent pedal feel on a long downhill or at the end of a fast motorway overtake. Dropping rotating and unsprung mass at the front sharpens turn-in as well. The Sport compound adds bite and a wider heat range over Street for fast-road work, while Racing carries the system into circuit temperatures. Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone available, visible through the F15’s typically large-diameter alloys; whether that matters to the buyer comes down to how the rest of the car is presented.

About the Hollow Front Brake Kit

The Hollow series applies an uprated front brake philosophy to platforms where factory specification was sized for normal operating envelopes rather than extended hard use. Front fitment across the F15 generation targets the axle bearing the greatest stopping load; the kit is configured to work across the range’s engine variants, from the 218bhp 25d to the 450bhp xDrive50i, rather than being calibrated for a single power output. The caliper body is hollow-cast as standard, with an optional Hollow Racing caliper, no dust cover, a 1000C rating and a two-year warranty, for serious track use. Three compounds give owners a genuine choice between road comfort, spirited road use and track deployment: not a marketing segmentation exercise but a practical response to how differently those use cases load a brake system. Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150 and premium polished-forged Titanium, Polished Gold and Polished Silver plus candy Teal, Blue, Red and Orange. Discs come drilled or slotted at the same price, and centre bells can be two-tone anodized in five colours or titanium, allowing the hardware to sit coherently with a specific wheel and body combination.

Fitment for the Bmw X5 F15 (2013-2018)

This kit covers the BMW X5 F15 platform from its 2013 introduction through the end of the generation in 2018, ahead of the G05’s arrival. Buyers on M-Sport specification should confirm their existing front disc diameter before ordering, as the M-Sport brake package fitted larger factory discs at the point of build, which can affect caliper carrier dimensions. Confirm your variant’s front brake specification before purchase if there is any uncertainty.
