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

A loaded F15 X5 tips well past two tonnes, and on a vehicle that heavy the job of hauling it down is shared by all four corners, the rear axle included. On long motorway descents, with a trailer on the back, or during repeat stops on a hot trackday, the standard rear discs heat-soak quickly and the pedal starts to lengthen. That is exactly the failure mode this kit is built to push back against.

The XYZ Racing Hollow Rear Brake Kit upgrades the rear axle of the 2013-2018 BMW X5 F15 with a two-piece, hollow-vane disc and a fixed performance caliper, supplied as a matched left-and-right pair. It gives you more thermal headroom and a firmer, more repeatable pedal under sustained heavy braking. It is a rear big brake kit aimed at owners who actually work the car, not those chasing a cosmetic tweak alone.

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

The first thing you notice is pedal consistency. The hollow-vane disc design sheds heat faster and carries less rotating mass than a comparable solid item, so the brakes recover between stops instead of stacking heat until they fade. On a car this heavy, that shows up as steadier stopping on a downhill run or under tow. The lighter two-piece construction also trims unsprung mass at each rear corner, so the suspension settles the axle more cleanly. The three pad compounds let you match the kit to how you drive: Street for quiet everyday use, Sport for spirited road work, and Racing where outright bite and fade resistance matter most. Matching the rear compound to the front keeps the brake balance steady under trail braking. Behind the rear wheels the caliper is painted in Red, Yellow, Gold, Black or Anodized Black at no extra cost, so the look follows the function.

About the Hollow Big Brake Kit

This is a rear-axle big brake kit built around a two-piece floating disc with a hollow-vane braking ring, where material is cored out internally to cut rotating and unsprung weight while opening extra cooling paths through the disc body. Less mass at the wheel lets the suspension respond more cleanly, the floating bell lets the ring expand under heat without distorting, and better cooling keeps the friction surface inside its working temperature range for longer. The disc pairs with a fixed caliper sized for the F15’s rear axle and supports three pad compounds, Street, Sport and Racing, so one set of hardware spans daily driving through to circuit use. The caliper body is hollow-cast as standard, with a Hollow Racing upgrade available for hard track use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Painted caliper finishes run from subtle Anodized Black to bright Yellow or Gold, with premium polished-forged and candy options and a custom Pantone choice for owners matching a specific scheme. Discs are offered drilled or slotted at the same price, braided lines are included, and the centre bell can be upgraded to a two-tone anodized colour or titanium. Everything here is specified for the rear of the car, complementing a front upgrade rather than replacing it.

Fitment for the BMW X5 F15 (2013-2018)

This kit fits the F15-chassis BMW X5 built from 2013 to 2018 and mounts to the rear axle as a left-and-right pair. Confirm your car carries the F15 chassis code and falls inside that model-year span before configuring. As this is the rear-axle kit, pair it with the matching front kit if you want balanced stopping power at both ends.
